As is shown in the figure, water is contained in a big reservoir. Electric power of the pump is 1.5 kw, and the efficiency is 75% (75% of the electric energy consumed by pump is transferred into mechanical energy). Diameter of the tube is 0.0525 m. Volumetric flow rate is 0.379 m^3/min. Density of water is known as 1000 kg/m^3, viscosity of water is known as 1 cp. Calculate the friction losses in the pipeline ( Ev and Ev).
