Water at 15°C is to be discharged from a reservoir at a rate of 18 L/s using two horizontal cast iron pipes. connected in series and a pump between them. The first pipe is 20 m long and has a 6-cm diameter, while the second pipe is 34 m long and has a 3-cm diameter. The water level in the reservoir is 30 m above the centerline of the pipe. The pipe entrance is sharp-edged, and losses associated with the connection of the pump are negligible. Neglecting the effect of the kinetic energy correction factor, determine the required pumping head and the minimum pumping power to maintain the indicated flow rate. The density and dynamic viscosity of water at 15°C are rho = 999.1 kg / (m ^ 3) and mu=1.138*10^ -3 kg/m* s . The loss coefficient is KL = 0.5 for a sharp-edged entrance. The roughness of cast iron pipes is epsilon = 0.00026r .
