A venturimeter is in an installation of 100 mm diameter pipe carrying water. The maximum range available in water-mercury differential pressure gauge is 50 cm of mercury deflection. Find the maximum throat diameter which will induce full gauge deflection when the flow rate is 20 litres/s. Assume C,= 0.984.

solve a and b.

Transcribed Image Text:a) A venturimeter is in an installation of 100 mm diameter pipe carrying water. The maximum
range available in water-mercury differential pressure gauge is 50 cm of mercury deflection.
Find the maximum throat diameter which will induce full gauge deflection when the flow
rate is 20 litres/s. Assume C;= 0.984.
b) Figure 5 shows a turbine with inlet pipe and a draft tube. If the efficiency of the turbine
is 80% and discharge is 1000 litres/s. Assuming no losses, find:
1. The power developed by the turbine.
2. The reading of the gauge G.
