4. Attempt any five questions
a) Differentiate between viscosity and kinematic viscosity? State their unit of measurement pressure?
b) What do you mean by single column manometers? How are they used for measurement of pressure?
c) Differentiate between
a. Steady and unsteady flow
b. Uniform and non-uniform flow
d) Discuss the factors influencing the loss f energy due to friction
e) Discuss the construction and working of hydraulic accumulator.
f) Explain construction and working of gear pump.
g) Explain how a venturimeter can be used to measure discharge.
Note : Attempt any two questions
a. Calculate the density, specific weight of 5 litre of petrol of specific gravity 0.75
b. An orifice meter with orifice diameter 100mm is inserted in a pipe of 200mm diameter. The pressure gauges fitted upstream and downstream of the orifice meter fives reading of 19.62 N/cm2 and N/cm2 respectively. Coefficient of discharge for the meter is given as 0.6 find the discharge of water through pipe.
