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.
Italicized values are from steam tables.
Bold values are calculated. Then the first law can be used to determine the required shaft work and heat transfer. 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. Bold values are calculated.
