3. A 1.5 kW pump delivers 1.2 kg/s water to a building. The water comes in at 100 kPa, and 15°C. The outlet water velocity must be 30 m/s and the pump has an isentropic efficiency of 75%. What is the maximum exit pressure the pump can produce? (Answer: 587.5 kPa) *Hint: The Mechanical Energy Balance may be making a return on this problem!
