Hello. Can you help me to solve this problem by providing detailed steps/explanations? Thank you.

Water at 20 C is being pumped from a storage tank to an elevated tank at the rate of 5.0 x 10-3 m/s. All the pipes used, as shown in the figure below, are 4 inches (100 mm) Schedule 40 pipes [1]. The pump has an efficiency of 65%. 100 m 15 m 50 m 4-in, pipe pump Question 8.2.a [20 Points] Calculate the kW power needed for the pump. Question 8.2.b [20 Points] Consider that the pump power is known as you have solved in answering Question 8.2.a, but now the flow rate is unknown. Solve for the flow rate
