Question

Liquid water at 70F enters a pump with a volumetric flow rate of 7.71 ft3 /min through an inlet pipe having a diameter of 6 in. The pump operates at steady state and supplies water to two exit pipes having diameters of 3 and 4 in., respectively. The mass flow rate of water in the smaller of the two exit pipes is 4 lb/s, and the temperature of the water exiting each pipe is 72F. Determine the water velocity in each of the exit pipes, in ft/s.

Answer 1

for 3 in. velocity is 1.31 ft/s

for 4 in. velocity is 0.737 ft/s
