A Francis turbine is installed with a vertical draft tube. The top of the draft is 1.0 m below thecenter line of spiral casing while the tail race water level is 3.0 m from the top of the draft tube. There is no velocity of whirl at the top or bottom of the draft tube and leakage are negligible. Theelevation of water from the reservoir to the center line of the turbine spiral casing is 50 m, and watervelocity at the inlet is 5 m/sec. Discharge is 2.5 cu.m/sec, hydraulic efficiency is 86%, overallefficiency of 83%. Determine the reading of a pressure gage (in psi) if one is installed at thepenstock just before the water inlet to the turbine.

I need help on this question: According to the question: a) If the pipe connected to the pump inlet has a diameter of 24 mm with length (LCP) of 5 m and Darcy friction factor of 0.03, what would be the actual head rise across the pump for a case where the pump outlet pressure is 200 kPa? The difference in height between pump inlet and outlet is 0.25 m, the tank exit is sharp-edged, and the water level in the tank to the tank exit pipe (HWL) is 2 m. Also, consider that the flow velocity inside the tank is negligible. The value of the actual head rise across the pump is = ? b) What would be the pump motor power if the efficiency is 60%? The value of the pump motor power is = ?
