A diffuser is an integral part of a water pump. The diameter at the entrance to the diffuser section is 30 mm and the diameter at the exit is 45 mm. Water at 300 K flows through the pump at 2.2 kg/s. Determine the pressure rise in kPa and psi associated with the diffuser.

Assume that the water is incompressible and use the specific volume and specific internal energy for saturated liquid water at 300 K.
