2. Water from a reservoir is pump over a hill through a pipe 900mm in diameter and a pressure of one kg/cm² is maintained at the pipe discharge where the pipe is 85m from the pump centerline. The pumps have a positive suction head of 5m. Pumping rate or the pump at 1000 rpm is 1.5m³/sec. Friction losses is equivalent to 3m of head loss. What is the head that should the pump cover for the system?

2. An inclined venturi tube containing water has an inlet of 300 mm diameter and a throat of 150 mm diameter. The difference in head between the inlet and the throat is 250 mm. Neglecting losses, calculate the discharge through the venturi meter. Alir 250 mm 300 mm Diam 150 mm Diam -Water
