A pump is used to transfer water (p=1000 kg/m) from a lake to a reservoir as shown in Figure 3 (b). The piping system consists of a cast iron pipe with the diameter, D of 60 mm and the total length of the pipe is 16 m. If the pump operates at 400 L/min with 45% efficiency, determine: i) the total head loss of the pipe, and ii) the actual power of the pump used in this system.
