On a property, water is pumped from point A at the bottom of a hill to point B on top of the hill via a cast iron pipe at a flow rate of ?=Q= 0.06 ?3/?m3/s. The total pipe length is 173 ?m of diameter 0.14 ?m, and the elevation difference between A and B is 27 ?m. Between points A and B it is required to use 20 of the 90?90o flanged smooth bends (???=KLB= 0.19) and 5 of the fully open gate valve (???=KLG= 0.22). The entrance and exit losses are 0.54 and 1.3, respectively. Calculate the minimum pump power required to pump water from A to B, given that the pump efficiency is 0.76.    Density and viscosity of water are 1000 ??/?3kg/m3 and 0.00131 ??/?.?kg/m.s, respectively.
