Question:
An inventor proposes to produce mechanical power from 50 kg/s of geothermal water (Cp = 4.2kJ/ kg - K) at 365K. The water stream is at the ambient pressure of 100 kPa.
(a) Assuming To=300K, what is the maximum possible mechanical power output (in kW)?
(b) An actual heat engine design is tested and found to produce 450 kW from the geothermal water stream. What is the second law efficiency achieved?
