Problem 3 (20 Marks): A 70 percent efficient pump delivers water at 208C from one reservoir to another 20ft higher, as in Fig. The piping system consists of 60ft of galvanized iron 2 -in pipe, a reentrant entrance, two screwed 90 long-radius elbows, a screwed-open gate valve, and a sharp exit. What is the input power required in horsepower with and without a 6 well-designed conical expansion added to the exit? The flow rate is 0.4ft3/s
