Cavitation Demonstration is a small scale apparatus designed to demonstrate Cavitation utilizing an Hydraulics Bench
Flow control valves upstream and downstream of the test section allow flow conditions to be optimised for the demonstration of Cavitation
The apparatus consists of a circular Venturi shaped section manufactured from clear acrylic
Three Bourdon gauges indicate the static pressure upstream of the contraction, inside the throat and downstream of the expansion
Educational software available as an option
Quick release fitting for easy connection to hydraulics bench.
The permanent arrangement of PVC pipes and fittings is mounted on a freestanding support frame that is designed to stand alongside Hydraulics Bench in use.
Self-sealing quick release fittings at strategic points in the network allow rapid connection of the digital hand-held pressure meter, allowing appropriate differential pressures to be measured. Flow leaving any of the outlets in the network is measured using the volumetric facility incorporated on the Hydraulics Bench.
All clear acrylic test pipes are installed using threaded unions with 'O' ring seals that allow the pipes with different diameters to be repositioned without the use of tools.
Isolating valves allow a wide range of different series, parallel and mixed pipe configurations to be created without draining the system. Flow into the network and flow out from the network at each outlet can be individually varied to change the characteristics of the system.
A free standing unit developed to demonstrate the phenomena of pipe surge & water hammer when connected to a Hydraulics Bench.
Electronic sensors used to measure pressure transients at two locations in the water hammer test pipe, one adjacent to fast acting valve and one half way along the test pipe.
Includes two separate stainless steel test pipes, both 3m long, constant head tank, slow acting valve, fast acting valve etc
Straight metal pipes used, rather than a coiled arrangement, to minimize distortion to the pressure profile
A transparent surge shaft (40 mm diameter and 800mm high) with scale allows transient water levels to be observed and timed
Pressure transients monitored using a PC (not supplied) using a USB connection from the pressure transducers (requires no external electrical supply).
The Flowmeter Measurement Apparatus consists of a Venturi meter, variable area meter and orifice plate, installed in a series configuration to permit direct comparison. Pressure tappings are incorporated so that the head loss characteristics of each flow meter may be measured. Pressurisation of the manometers is facilitated by a hand pump. These tappings are connected to an eight tube manometer bank incorporating a manifold with air bleed valve. A flow control valve permits variation of the flow rate through the circuit.
The bench is used as the source of water supply and for calibrating volumetrically each flow meter. The circuit and manometer are attached to a support framework which stands on the working top of the Hydraulics Bench.
It is used for physics student experiment in group at middle school to study melting and solidification process of naphthalene.

Boundary layer growth is determined by the measurement of the velocity profile at four stations along the pipe using a traversing Pitot tube.
A bend or mitred cascade elbow may be fitted mid way along the smooth wall pipe for comparison of pressure losses.
Air enters the smooth walled pipe through one of the two flow measurement nozzles provided. Pressure tappings along the length of the pipe permit the pressure gradient to be determined.
The equipment includes a long smooth walled pipe joined to the suction side of an electrically operated centrifugal fan. The fan discharge pipe terminates in a flow control damper for closed conduit work or a plate containing a small aperture for jet dispersion measurements.
A conventional flow measuring orifice plate is supplied for installing in the pipe upstream of the fan for additional demonstrations of pressure loss and recovery.
The equipment is mounted on a floor standing steel frame with an adjacent support for the extended suction pipe. Pressure measurements are made on a multi-tube inclinable manometer mounted on the support frame.
Air jet studies are carried out on the discharge side of the fan. A Pitot tube is traversed vertically and horizontally at different distances from the discharge orifice to investigate the dispersion properties.
The test section consists of a classical Venturi machined in clear acrylic. A series of wall tappings enable 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.
The Venturi can be demonstrated as a means of flow measurement and the discharge coefficient can be determined.
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.
A clear understanding about the physical properties of fluids is essential before studying the behaviour of fluids in static or dynamic applications.
This apparatus introduces students to the following properties of fluids:
Capillarity - capillary elevation between flat plates and in circular tubes
Density and relative density (specific gravity)
Viscosity
Atmospheric pressure
Buoyancy (Archimedes principle).

This Pascals Apparatus, developed to demonstrate principle of Pascal, consists of a machined body incorporating a horizontal flexible diaphragm to which one of three alternative glass vessels can be fitted. 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. 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 spirit level indicates when the lever arm is horizontal and therefore balancing the force / pressure at the base of the vessel. 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.
