Q1. In the figure shown, there are 40-m of 5-cm pipe, 25-m of 15-cm pipe, and 45- m of 7.5-cm pipe, all cast iron. There are two 90° elbows and an open globe valve, all flanged. (1)If the exit elevation is zero, what power is extracted by the turbine when the flow rate is 4.51/s of water at 20°C? (2)To increase the power extracted by 30%, how much upstream level must we use and what will be the flow in the system then? Elevation 30m Sem Turbine Open Globe 15cm 7.5cm
