A pump delivers water at a temperature of 20 °C from one reservoir to another high reservoir. The water level difference between the two reservoirs is 6 m. A galvanized iron piping system consists of a 20 m delivery pipe, 10 cm diameter, a reentrance entrance, two long sweep elbows 90°, and an exit. Sketch the diagram with the relevant hydraulic and energy grade line. With the help of a Moody chart given in the Appendix, determine the pump efficiency required by the pump's in Q3(a) if the pumping power and flow rate are 2 kW and 40 m³/h, respectively.
