Water at 50°F is pumped from a lake at 750 gpm through a length of 3-inch schedule 40 commercial steel pipe as shown below. The inlet to the pipe is eight feet below the surface of the lake. A 25-HP gasoline engine drives the pump and the pump has an efficiency of 80% What is the Reynolds number in the pipe? Is the flow laminar or turbulent? What is the head added to the water by the pump? What is the head loss due to pipe friction?
