Problem 2: (20pts). Water (=1000kg/m3,=1103Pa.s) is pumped from a large diameter reservoir open to atmosphere to a height of 1200m from the reservoir level, through a pipe of 5cm I.D. at an average velocity of 5m/s. The pipeline along with the fittings is equivalent to 2500m long and the overall pump efficiency is 70%. Answer the following questions: a. Calculate Frictional losses per unit weight b. Calculate the pumping power in kW
