| Leading Manufacturer and Exporter of Fluid Machnics-Basic Principles such as Dead Weight Pressure Gauge Calibrator, Hydrostatic Pressure, Metacentric Height, Fluid Statics & Manometry Apparatus, Fluid Properties Apparatus, Pascals Apparatus and many more items from Ambala. |
|
This calibrator functions on the same principle adopted in calibrating industrial pressure gauges. This dead weight pressure gauge calibrator consists of a precision machined piston and cylinder assembly mounted on levelling screws. A Bourdon gauge is supplied for calibration. The weights supplied are added to the upper end of the piston rod which is rotated to minimise friction effects. The gauge is thus subject to known pressures which may be compared with the gauge readings and an error curve drawn. |
The Hydrostatic Pressure accessory has been designed to determine the static thrust exerted by a fluid on a submerged surface and allow comparison of the measured magnitude and position of this force with simple theory. A fabricated quadrant is mounted on a balance arm which pivots on knife edges. The knife edges coincide with the centre of arc of the quadrant. Thus, of the hydrostatic forces acting on the quadrant when immersed, only the force on the rectangular end face gives rise to a moment about the knife edges. The balance arm incorporates a balance pan for the weights supplied and an adjustable counterbalance. This assembly is mounted on top of an acrylic tank which may be levelled by adjusting screwed feet. Correct alignment is indicated on a circular spirit level mounted on the base of the tank. An indicator attached to the side of the tank shows when the balance arm is horizontal. Water is admitted to the top of the tank by a flexible tube and may be drained through a cock in the side of the tank. The water level is indicated on a scale on the side of the quadrant. |

This equipment allows a thorough investigation of the factors affecting the stability of a floating body. On this item the position of the metacentre can be varied to produce stable and unstable equilibrium. The equipment consists of a plastic rectangular floating pontoon, the centre of gravity of which can be varied by an adjustable weight which slides and can be clamped in any position on a vertical mast. A single plumb-bob is suspended from the mast which indicates the angle of heel on a calibrated scale. A weight with lateral adjustment allows the degree of heel to be varied and hence the stability of the pontoon determined. The equipment does not require a separate water tank as it may be used on the Hydraulics Bench by filling the volumetric tank. |

The Pascal’s apparatus provides a simple demonstration that the pressure in an incompressible fluid varies with depth and does not depend on the shape of the container. This apparatus, designed to demonstrate Pascal’s principle, consists of a machined body incorporating a horizontal flexible diaphragm to which one of three alternative glass vessels can be fitted. The diameter at the base of each vessel is common but the shape of each vessel varies; one parallel sided, one conical and one tapering inwards. The diaphragm, located at the base of the vessel, conveys the force from the water inside the vessel to a lever arm with a sliding counterweight. A spirit level indicates when the lever arm is horizontal and therefore balancing the force / pressure at the base of the vessel. The force on the diaphragm depends on the depth of water above the diaphragm and the area of the diaphragm that is constant for all three vessels. A height adjustable pointer allows each of the vessels to be filled to the same depth so that the force / pressure can be shown to be common for all three vessels, independent of shape. |

The Bernoulli's Theorem Demonstration accessory illustrates those circumstances to which Bernoulli's Theorem may be applied. Also, separately, why in other circumstances the theorem gives an inadequate description of the fluid behaviour. The test section consists of a classical Venturi machined in clear acrylic. A series of wall tappings allow measurement of the static pressure distribution along the converging duct, while a total head tube is provided to traverse along the centre line of the test section. These tappings are connected to a manometer bank incorporating a manifold with air bleed valve. Pressurisation of the manometers is facilitated by a hand pump. The test section is arranged so that the characteristics of flow through both a converging and diverging section can be studied. Water is fed through a hose connector and is controlled by a flow regulator valve at the outlet of the test section. The Venturi can be demonstrated as a means of flow measurement and the discharge coefficient can be determined. |
This equipment allows the force developed by a jet of water impinging upon a stationary object to be measured. The apparatus consists of a cylindrical clear acrylic fabrication with provision for levelling. Water is fed through a nozzle and discharged vertically to strike a target carried on a stem which extends through the cover. A weight carrier is mounted on the upper end of the stem. The dead weight of the moving parts is counter-balanced by a compression spring. The vertical force exerted on the target plate is measured by adding the weights supplied to the weight pan until the mark on the weight pan corresponds with the level gauge. A total of four targets are provided: a flat plate, a 120° cone and a hemispherical cup. |

This equipment permits calibration of two orifices of differing diameter. In the Orifice & Free Jet Flow accessory a constant head tank is fed with water from the Hydraulics Bench. The orifice is installed at the base of this tank by means of a special wall fitting which provides a flush inside surface. The head is maintained at a constant value by an adjustable overflow and is indicated by a level scale. A jet trajectory tracing device allows the path followed by the jet to be ascertained. Adjustable feet permit levelling. |
The Orifice Discharge accessory enables full analysis of the flow through five different orifices over a range of flow rates. The Orifice Discharge accessory consists of a cylindrical glass tank which has an orifice fitted in the base. A traverse assembly is provided which enables a pitot tube to be positioned anywhere in the jet. Attached to this pitot tube is a sharp blade which can be traversed across the jet to accurately measure the jet diameter and the vena contracta diameter and so determine the contraction coefficient. The pitot head and the total head across the orifice are shown on manometer tubes adjacent to the tank. In addition to the standard orifice, supply includes four additional orifices.These are supplied in an attractive storage case. A label inside the lid gives dimensional details of each orifice. |

This item is intended to reproduce the classic experiments conducted by Professor Osborne Reynolds concerning the nature of laminar and turbulent flow. The equipment operates in a vertical mode. A header tank containing stilling media provides a constant head of water through a bellmouth entry to the flow visualisation pipe. Flow through this pipe is regulated using a control valve at the discharge end. The flow rate of water through the pipe can be measured using the volumetric tank (or measuring cylinder) of the Hydraulics Bench. Velocity of the water can therefore be determined to allow calculation of Reynolds' number. The equipment uses a similar dye injection technique to that of Reynolds' original apparatus to enable observation of flow conditions. |

This accessory is designed to introduce students to three basic types of flow meter. The equipment consists of a Venturi meter, variable area meter and orifice plate, installed in a series configuration to permit direct comparison. A flow control valve permits variation of the flow rate through the circuit. Pressure tappings are incorporated so that the head loss characteristics of each flow meter may be measured. These tappings are connected to an eight tube manometer bank incorporating a manifold with air bleed valve. Pressurisation of the manometers is facilitated by a hand pump. The circuit and manometer are attached to a support framework which stands on the working top of the Hydraulics Bench. The bench is used as the source of water supply and for calibrating volumetrically each flow meter. |

This equipment is designed to produce and measure the characteristics of free and forced vortices. The apparatus comprises a clear acrylic cylinder on a plinth designed to produce and measure free and forced vortices. The free vortex is generated by water discharging through an interchangeable orifice in the base of the cylinder and the resulting profile is measured using a combined caliper and depth scale. The forced vortex is induced by a paddle in the base of the cylinder which is rotated by jets of water. The profile of the forced vortex is determined using a series of depth gauges. Velocity at any point in the free or forced vortices may be measured using the appropriate pitot tube supplied. Dye crystals (not supplied ) may be used to demonstrate secondary flow at the base of the free vortex. |

This demonstration turbine provides a simple low cost introduction to the Francis inward flow reaction turbine showing its construction, operation and performance. • Francis runner surrounded by 6 guide vanes inside PVC volute with clear acrylic front panel for visualisation • Guide vanes adjustable when turbine is running with scale to indicate degree of opening and clamp to prevent movement • Francis runner 60 mm diameter with 12 blades • Brake force determined using Prony type brake dynamometer • Inlet pressure gauge with range 0 to 2 bar • Educational software as an option A tapering, spiral shaped volute conveys water to the runner via a ring of guide vanes that are adjustable in angle to vary the flow through the turbine. Water enters the runner tangentially at the periphery, flows radially inwards through the blades towards the hub then exits axially via a draft tube. Power generated by the turbine is absorbed by a Prony friction brake consisting of a pair of spring balances attached to a brake belt that is wrapped around a pulley wheel driven by the runner. The load on the turbine is varied by tensioning both spring balances which increases the friction on the pulley wheel. Brake force is determined from the difference in the readings on the two spring balances and the torque calculated from the product of this force and the pulley radius. The head of water entering the turbine is indicated on a Bourdon gauge and the speed of rotation is measured using a non-contacting tachometer (not supplied). The volute of the Francis turbine incorporates a transparent front cover for clear visualisation of the runner and guide vanes and is designed to complement the F1-25 Pelton turbine. |

This unit is designed as a portable and self-contained service module for the range of accessories described later in this data sheet. The bench is constructed from lightweight corrosion resistant plastic and is mounted on wheels for mobility. The bench top incorporates an open channel with side channels to support the accessory on test. Volumetric measurement is integral and has been chosen in preference to other methods of flow measurement for its ease of use, accuracy and safety in use (no heavy weights for students to handle). The volumetric measuring tank is stepped to accommodate low or high flow rates. A stilling baffle reduces turbulence and a remote sight tube with scale gives an instantaneous indication of water level. A measuring cylinder is included in the supply for measurement of very small flow rates. A dump valve in the base of the volumetric tank is operated by a remote actuator. Opening the dump valve returns the measured volume of water to the sump in the base of the bench for recycling. An overflow in the volumetric tank avoids flooding. Water is drawn from the sump tank by a centrifugal pump and a panel mounted control valve regulates the flow. An easy-to-use quick release pipe connector situated in the bench top allows for the rapid exchange of accessories without the need for hand tools. Each accessory is supplied as a complete piece of equipment needing no additional service items other than the Hydraulics Bench. When coupled to the bench they are immediately ready for use. |
