A pump is pumping water at a flow rate of 1200 litres per minute. In the pump the mechanical energy of the water increases by 250 J/kg. The density of water is 1000 kg/m3. a) Determine the pressure difference between the pump outlet and the pump inlet. Assumptions: there are no frictional losses in the pump, and differences in velocity and elevation between inlet and outlet of the pump can be neglected. b) Show that the mechanical power added to...

A pump increases the water pressure from 100 kPa at the inlet to 900 kPa at the outlet. Water enters this pump at 15 degree 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 degree C?
