Water substance at 70 bar and 65°C enters a boiler tube of constant inside diameter of 35 mm. The water leaves the boiler tube at 50 bar and 700 K at velocity of 150 m/s. Calculate the inlet volume flow (liters/s). From steam tables: @ 70 bar (7Mpa) and 65°C: υ1 = 0.001017 m3 /kg @ 50 bar (5Mpa) and 700 K (427°C): υ2 = 0.06081 m3 /kg

A pump in a municipality's water-supply system receives water from the filtration beds and pumps it up to the top of a water tower. The tower's height is 35m, and the inlet piping to the pump is 2m below the pump's intake. The water temperature is 20C, measured at the both the inlet and the discharge from the pump. The mass flow rate through the pump is 100 kg/s, the diameter of the inlet piping is 25cm, and the diameter of the discharge piping is 15cm. Determine the power required by the pump.
