Problem 1: Steam is heated in closed system from 20 bar, 300 °C to 450 °C. Determine the amount of heat and work in the following cases:

a) Heating is conducted at constant pressure.

b) Heating is conducted at constant volume. What is the final pressure?

c) Use these results to estimate the CP and CV of steam. The process may be assumed to be mechanically reversible.

Problem 2: Wet steam at 200 °C with 80% moisture is heated by removing 600 kJ/kg of heat.

a) Determine the final state (pressure and temperature and quality, if a two-phase system) if cooling is at constant pressure.

b) Determine the final state if cooling is at constant volume.
