Problem 5) You are pumping water at 20 °C from a large lake, up to a reservoir. You may assume the water levels do not change in either body of water. You are using the roughest possible concrete pipe with an inside diameter of 30 cm. The velocity in the pipe is 5 m/s. There are some obstacles in your way and you build up and over them with 90° elbows. What pump power do you need? (ans≈ 386 kW) 10 m 0m 200 m 5m 55 m 60 m
