Water enters a pipe at 90 kPa, 25oC and a velocity of 10 m/s. At the exit the pressure is 500 kPa and velocity is 12 m/s while the temperature remains unchanged. If the volume flow rate is 10 m3/min both at the inlet and exit, determine the difference of flow rate of energy (J) between the exit and inlet. What-if Scenario: What would the answer if the exit velocity were 15 m/s instead?
