Fluid Mechanics Physics Equipments

Demonstration type, fully enclosed in a transparent synthetic case for demonstration. 100 mm coated dial reads from 28 to 32 inches and 950 to 1040 millibars, air tight sealed all around, pressure rubber bulb provided to force the movements, for educative demonstration.

The whole column of mercury is visible. Scale is graduated in both English & metric systems. Zero point adjustment is carried by a screw clamp attached to glass tube. Complete fitted on a polished wooden board.

To demonstrate that when a liquid flows through a tube having a constriction, the speed of flow is increased and pressure decreased in the constricted section..

A horizontal tube 500 mm long 12mm O.D. is constricted near its centre and short side tubes are provided in each section for attaching glass manometer tubes 270 x 8 mm bore. If a constant head device is used to send a flow of water through the horizontal tube the variation of pressure in various sections may be determined.

Circular gauge reads 0 to 50 lb./in x 1 & o to 3.5 Kg/cm x 0.1 actual (total) pressure with clear perspex back so that the working parts may be seen.

To demonstrate floating, suspension, & sinking in accordance with Archemede’s principle. Made of glass.

The apparatus comprises of four different shapes limbs projecting vertically from a common horizontal tube made of glass mounted on wooden/plastic round stand.

A working model to demonstrate the principles involved in the action of a force-pump.

Cylinder is 25 x 350 mm dia x overall height. It is provided with a non-return float valve at its lower end. Lower part of the cylinder has an outlet side tube communicating with the lower end of another cylinder also equipped with non-return valve. Outlet tube from the secondary cylinder is drawn out into a jet to demonstrate ability of force pump to eject water at high pressure.

A glass tube of 6mm bore is enclosed in an enamelled and lacquered brass case, mounted on a polished wooden board with plates for fixing on wall. Open plate reflectors, ring and screws for vertical adjustments. A dual scale graduated in 25 to 32 inches and 640 to 810mm is read by verniers moving by rack and pinion, reading to 0.002 inch and 0.1mm are enclosed in a glass cylinder. A glass cistern at the lower end of barometer is provided with an ivory point to adjust the level of mercury. A thermometer -10 to 50C is provided on the wooden board. Supplied without mercury and glass case.

The apparatus comprises a pumping cylinder dia 25mm x 350mm overall height, provided with a piston and a non return valve at its lower end. A side tube joined at lower end of cylinder is also provided with a non return valve.

Pipette type, comprising glass float calibrated having coloured zones for charged, partly charged and uncharged conditions. Compressible bulb and rubber tube with fittings to glass body.

Having range of 60 degrees, made of glass with parallel graduated stem and shot-loaded bulb.

Jolly Air Thermometer bulb of mounted on a wooden frame that can be fixed at three places – up, middle , & down on the stand.
