Volumetric analysis of a hydrocarbon combustion product shows 8% CO2, 15% H2O (vapour), 5.5% O2 and 71.5% N2. The combustion product flows steadily through a heat exchanger at 200 kPa pressure. Assume each component in the mixture to be an ideal gas. In order to avoid the condensation of H2O in the heat exchanger, the minimum allowable temperature (in oC) is ______. Saturated H2O Table: P (kPa) 10 20 30 40 50 T (oC) 45.83 60.09 69.12 75.82 81.35
