Water flows steadily through a variable diameter insulated pipe. At the inlet, the velocity is 20 m/s and at the exit, the flow area is half of the inlet area. If the internal energy of water remains constant, determine the change in pressure between the inlet and exit. Assume water density to be 1000 kg/m3.
