Fluid Mechanics Physics Equipment

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.

This apparatus is designed to demonstrate to students that volume of air enclosed in the column is clearly visible to students. A wide bore glass tube is mounted vertically in front of a scale graduated 0-60 cm.

Zero corresponds to the inside of the closed top end of the tube. Air is confined in the tube by a coloured oil contained in a metal container fitted with a Bourden type gauge. A tap is fitted to the side of the metal container, for the air inlet tube from the pump. As the pressure in the oil container is increased, oil is forced into the glass tube and volume of contained air and its actual total pressure are directly indicated. The tube is of extra strong glass having very large safety overload margin. As a further precaution, a safety plastic screen is secured over the front. Overall ht. 690 mm approx. Supplied complete with oil.

To demonstrate the transmissibility of fluid pressure. The apparatus comprises two metal cylinders 15 mm and 30 mm dia respectively fitted with piston and connected by a tube. The pistons are provided with rods terminating in plate forms for loading with masses required. The complete apparatus is fitted on a wooden base.

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.
