Oil with the density of 950 kg/m and the kinematic viscosity of 2x10-5 m/s is pumped from a tank to another tank through a pipe, 113 m in length, 0.22 m in diameter, with the roughness of /D = 0.0002. The elevation change of the free surfaces of two tanks is 14.2 m. Loss coefficients at the pipe entrance and exit are 0.5 and 1.0, respectively, and the loss coefficients of two bends are 1.39 identically. What will be the useful pump power in [kW] delivered to fluid when flow rate is 0.3 m/s /s? The tolerance of your answer is 3%.
