2. A closed and rigid vessel containing air-water vapor mixture undergoes a cooling process with the volume of
2.172 m3, Fig.2. The operation conditions are summarized in Table 2. The dew point temperature of the
initial state is 99.63℃. Air behaviors as an ideal gas with specific heat ratio of 1.4. Determine (a) the initial
temperature of mixture Ti, in℃, (b) the initial pressure of mixture p1, in bar, (c) the mass of vapor, in kg,
(d) the mass of dry air, in kg, (e) the temperature of mixture T2 when water vapor starts to condensate, in ℃,
(D) the pressure of the mixture P2, in bar, as the mixture temperature reaches T2, (g) the heat transfer during
the cooling process, in kJ, (h) the entropy production during the cooling process, in kJ/K, if the vessel
boundary always keeps at a constant temperature of T2. (32%)
