2. A pump increases the water pressure from 100 kPa at the inlet to 1000 kPa at the outlet. Water enters this pump at 20°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? [MO1, MO2]
