A rigid 2 m^3 tank contains air at 160oC and 400 kPa and a relative humidity of 20%. Heat is removed until the final temperature is 120C. Determine the temperature at which condensation begins. [T=101C] Based on the calculations, is there any condensate formed during the process? Calculate the heat transferred from the tank. [Q= - 176 kJ] The internal energy of water vapor and water liquid is found from the tables. cv,a = 0.717 kJ/kgK and uv = ug (T).
