A centrifugal pump installation draws water from an open reservoir having a water elevation of 5 m above the pump centerline and delivers the water to another open reservoir 80 m above pump centerline. The rate of discharge is 600 li/min. The suction pipe has a diameter of 200 mm while that of the discharge pipe diameter is 150 mm. The friction loss at the suction is estimated to be 4 times the velocity head at the 200 mm suction pipe.

The diameter of the pipe is D=0.5 m and the dynamic viscosity of the fluid is u = 1.2 x 10-3 N.s/m, its specific mass is p=1000 kg/m. Since the cross-sectional average velocity of the flow in the pipe is V= 0.5 m/s, determine the type of flow.
