Question 1
A large turbine generates a power of 1000 kW under a head of 50 m. A 1/5th model of a hydraulic turbine is tested against a head of 10 m. The power developed (kW) and the discharge flow rate (m3/s) by the model are
Question 2
A water sprinkler has 8 mm diameter nozzle at either end of rotating arm. It is discharging water at right angle to the rotating arm in opposite direction at a velocity of 10 m/s. If the axis of rotation is at a distance of 0.2 m from one end and 0.24 m from other end then the angular velocity of arm is (neglect frictional effect).
