Work all problems.
All problems have equal weight.
Problem 1 Consider a pump providing water to the boiler of a steam power plant. Saturated liquid water enters the pump at 100 kPa. At the end of the exhaust the piston is at top dead center and the air in the cylinder is at 320 K and 100 kPa. The bottom dead center volume is 3 x 10 -4 m 3 and the compression ratio is 10.5. Problem 3 Consider a rocket engine which is to launch a rocket of mass 5000 kg to an elevation of 85,000 m.
