A Carnot Heat Engine (in a piston-cylinder configuration) uses 2.92 lbm. of water as a working substance. At the beginning of the isothermal expansion process, the water is at 80 psia and occupies a volume of 25 ft^3. The pressure and volume of the water at the end of the adiabatic expansion process are 14.7 psia and 120 ft^3, respectively. Calculate the following information:
a) the temp. of the high temp. reservoir.
b) the temp. of the low-temp. reservoir.
c) the pressure of the water at the end of teh isothermal expansion process.
d) the pressure of the water at the end of the isothermal compression process, and
e) the thermal efficiency of the cycle.
