Apump increases the water pressure from 100 kpa at the inlet to 900 kpa at the outlet. water enters this pump at 15°c through a 1-cm-diameter opening and exits through a 1.5-cm-diameter opening. determine the velocity of the water at the inlet and outlet when the mass flow rate through the pump is 0.5 kg/s. will these velocities change significantly if the inlet temperature is raised to 40°c?
