D Water is being pumped from a lower reservoir to an upper reservoir 45 m above, at arate of 30 litres per second, by a 24-kW (shaft) pump. If the head loss of the pipingsystem is 8 m, what is the mechanical efficiency of the pump? Assume water densityof 1000 kg/m3 and gravity acceleration 9.81 m/s2.
