Details of Experiment Performed :                                                

The apparatus is used to verify the Bernoulli’s Theorem.

System Type

The system is closed circuit.

The apparatus consists of:

>              A Centrifugal pump of 25mm x 25mm with 1/2 HP Motor (ISI – Kirloskar Make)

>              M.S. Sump Tank 80 Ltr. to collect the water.

>           M.S. Measuring Tank 30 Ltr fitted with piezometer tube to measure the discharge.

>           Damper is used to collect the water in M.S. MEASURING TANK for certain time.

>           G.I. pipe of internal dia 25mm and Gunmetal ISI mark Control Valve and regulating valves               are used to circulate water.

>           Bye-pass line is also used to regulate the discharge.

The apparatus consists of a variable area duct of perpex sheets with eleven piezometer, 7 tube (50cm height) fitted at equal distance. The duct is connected in between inlet and outlet tanks of size 25x 25 x 60cm each. The tanks are well fiber coated inside to prevent rust hence increase the life of tank.
