Product Details:

To demonstrate the effect of Bernoulli's theorem by studying variation in the pressure and speed of flow of an incompressible fluid through a tube with respect to the tube bore or cross-section. Comprises a Bernoulli's tube, with central constricted portion, a constant bore gradient tube, 6 lengths glass tubing, 2 swan necked outlets tubes and 8small pieces of rubber connecting tubing for joining various glass tubings as and when needed. The two flow tubes, each 500×13mm (L×OD) have three sealed-in short side tubes of length 25mm each with interspacing of about 150mm for connection to glass tubing lengths for use as manometers. The middle short side tube in Bernoulli's tube stem out from the central constricted portion for studying the effect of constriction.

Product Details:

Simple construction permits the use of water or even air for demonstration of the concepts involved. Comprises a pair of graduated glass syringes of capacities 50 and 20cm3, both having finely ground pistons and provide a cross-sectional area ratio of 3:1 respectively. Both the syringes mounted on a stable, non-skid sheet metal base with loading platform at their top and their nozzles linked to each other through a 3-position valve, by means of which they may be opened to the atmosphere, isolated or interconnected as desired. Both the pistons provided with limit-stop to prevent their complete ejection from the barrels. Thick wall of syringes makes it capable of withstanding pressures involved. The graduated syringe barrels also permit simple Boyle’s Law experiments to be performed.

Product Details:

A simple and economical apparatus for demonstration of Boyle's law to a fair degree of approximation. It consists of a graduated plastic syringe mounted on wooden block and a lubricated piston of the syringe mounted to another wooden platform that is capable of holding various weights. When loaded with different masses, piston compresses the air inside syringe increasing the pressure and corresponding volume can be read directly from syringe graduation.

Product Details:

Designed for Boyle's Law demonstration in wide pressure ranges to a group of students, results can be observed even from a distance. The apparatus comprises a thick walled, wide-bore glass tube mounted vertically in front of a scale graduated 0 to 65cm3, with closed end of the tube at the top and open bottom end secured tightly on the thick-walled metal tube with O-ring to get leak-proof joint. Other end of metal tube connected to a cylindrical oil chamber filled with coloredoilandcapableofwithstandinghighpressures.Zeroof the scale corresponds to the inside of the closed (top) end of the tube with the scale reading directly indicating volume of airenclosedinthetube. Oil chamber fitted with Bourdon gauge at the top, calibrated 0-3.4×105Nm-2andhasavalveononesideforconnectionto aircompressionpump. As the pressure in oil chamber is increased, oil is forced into the glass tube compressing the air contained therein and the volume of the contained air and its actual (total) pressure is directly indicated. The glass tube has thick walls of high strengthhavingaverylargesafetyoverloadmargin. A transparent safety screen is mounted securely in front of glass tube as an added safety measure.Supplied without pump and oil.

Demonstrates that sound waves need material medium for propagation and cannot travel through vacuum. For use on pump plates with diameter at least 15cm. It consists of an electric Bell operating on 4-6 voltsAC/DC, suspended inside bell jar through a pair of thick metal wires from a rubber bung that seals the jar from the top. The wires terminating in 4mm socket terminals on the upper side of rubber bung for electrical connection to the bell. 

Product Details:

For demonstration of the principle of hydraulic breaking system that operates on fluid pressure. It consists of a wheel with a handle for rotating it and hydraulically actuated breaking mechanism which is connected to cylindrical metal reservoir through a flexible pressure tubing. The plunger of the reservoir has a lever handle pivoted at its top for pushing it downward to apply pressure on the fluid inside, which is then forced through the connected tubing to actuate the braking mechanism. Complete apparatus mounted on a wooden base.
