To compare the experimental observations with published data such as in steam tables.
To investigate the relationship between the temperature and pressure of saturated steam.
Mounts vertically and spans the test section of an Educational Wind Tunnel
Angular position is adjustable
Comes with ample tubing
24 flush-mounted pressure taps around its circumference

It is microprocessor-controlled and contains a calibrated pressure transducer. The unit has an integral liquid crystal display that allows the user to read pressure directly. The signals ofthe pressure sensors may be output to optional Versatile Data Acquisition System. The Differential Pressure Transducer and readout is an optionalancillary to Subsonic Wind Tunnel. The control and instrumentation panel of the wind tunnel includes a location for mounting up totwo Differential Pressure Transducer modules. Using enables accurate real-time data capture, monitoring, display, calculation and charting of all relevant parameters on a suitable computer. It measures and displays pressures in Pitot-static tubes and other pressure-sensing devices fitted to a wind tunnel, with respect to the atmosphere or differential pressures. Many readings can be taken and the user may usea suitable spreadsheet software package to obtain a more accurate overview ofpressure distributions. When the Differential Pressure Transducer is used with the automatic dataacquisition unit it provides a significant advantage over conventional instruments such as manometers.

The equipment consists ofa vertical panel that holds a clear plastic quadrant, to which students addwater. The quadrant has engraved lines to help students keep the plane in avertical or angled position. The cylindrical sides of the quadrant have theircentral axis coincidental with the moment measurement axis. This product allows students to measure the moment due tothe fluid (hydrostatic) thrust on a fully or partially submerged plane. The plane works in either a vertical or inclined (angled) position. Students thencompare their measurements with theoretical analysis. The total fluid pressures on these curved surfaces therefore exert no moment about this pivot.Therefore, the moment is only due to the fluid pressure on the plane testsurface. Students measure this moment using weights suspended from a level arm. A scale on the panel of the apparatus shows the head of water. They then initially balance the quadrant tank using one of the weighthangers and the smaller trimming tank. They take results by balancingincremental weights on the hanger with known quantities of water. To performexperiments, students level the apparatus using its levelling feet and spirit(bubble) level. They decide whether to test either a vertical or inclinedplane. Students note the relationship between the moment and the water height(h). They then usethe results to calculate the equivalent moment of force (M) or hydrostaticthrust.

The unit has an integral liquid crystal display with a scroll switchthat allows all 32 channels to be viewed in groups of four at any time. Theconditioned outputs of the pressure sensors, and any other connected compatibleelectronic instruments, may be output to Versatile Data Acquisition System toallow computer based data acquisition and display. The 32-Way Pressure Display Unit is an optional ancillary tomodular Subsonic Wind Tunnels. The unit mounts onto the control and instrumentationframe of the wind tunnels. Connection to each of the 32 calibrated pressuretransducers is via quick-release pressure inputs mounted on the front panel ofthe unit. It measures and displays up to 32 pressures frommodels, Pitot-static tubes and other measuring instruments fitted to a windtunnel. It is ideally suited to applications where multiple pressuremeasurements are required, for example in boundary layer and tapped aerofoilmodel investigations. This allows easy and quick connection between the unit and anexperiment mounted in a wind tunnel. When the 32- Way Pressure DisplayUnit is used with the system it allows laboratory time to be used more efficientlybecause data can be captured and processed much more quickly than when usingmanual techniques. All pressures are measured with respect toatmosphere. Using enables accuratereal-time data capture, monitoring, display, calculation and charting of allrelevant parameters on a suitable computer. This option providessignificant experimental advantages over conventional instruments such asmanometers. The facility in the software to average data to remove thefluctuations inherent in wind tunnel measurements enhances the quality of theresults by making their interpretation much easier.

The apparatus comprises of two units: the manometer and gauge assembly and the calibration of a pressure gauge assembly. During test, calibration weights are placed onto the loading platform, which is an integral part of the piston assembly. All air is expelled from the system through a purge hole in the upper part of the cylinder. The internal mechanism of the gauge is clearly visible through the transparent dial.
The apparatus has been designed to allow the suction pressure or delivery pressure of a diaphragm pump to be measured on sloping or vertical manometers and Bourdon gauges, for comparison; and to investigate the calibration and internal workings of a Bourdon gauge.
