4. A pump delivers water (p=1000 kg/m3, kinematik viscosity v = 10-6 m/s) from one reservoir to another reservoir at 5.6 X 10-3 m/s through 120 m of 0.05-m- diameter pipe. See the figure below for several pipe-fittings installed on the pipe- line. The pipe is made up of commercial steel with roughness value &=0.046 mm. Calculate the power of the pump required for the water-transfer. The valves at b and e are gate valve (half closed) and globe valve (open), respectively. c is 90 elbow, standard Radius and d is 90 elbow long sweep. Z=8m 2 Pump e 40 m elevation from ground level
