Water enters a pump at 400000 Pa at a rate off1.5 ke/s. The water leaving the pump enters a turbine in which the pressure is reduced and electricity is produced.

The shaft power input to the pump is 2 kw and the shaft power output from the turbine is 2 kW Both the pump and turbine are 88 percent efficient. If the elevation and velocity of the water remain constant throughout the flow and the irreversible head loss is 1 m, Find the pressure of water at the turbine exit.
