The exam is open notes and open text book.
All problems have equal weight.
A rigid container holds 3 kg of air. The heat transfer is 200 kJ. Determine the final temperature, the change in internal energy, and the work. A desuperheater is an adiabatic mixing tank which produces saturated vapor from a superheated vapor by adding liquid. The nozzle inlet pressure is 400 kPa, the inlet kinetic energy is negligible, and the outlet pressure is 100 kPa.
