CH4 burns completely with the exact stoichiometric amount of air required. The air is supplied at 25C and 760mmHg, with a molal humidity of 0.025 . The combustion products leave at 480C and 800mmHg and are passed through a heat exchanger from which they emerge at 37C and 775mmHg. a) Draw a process diagram including all known information b) For the entering air, compute: 1. The absolute humidity 2. The relative humidity 3. The dew point c) How much water is condensed in the heat exchanger per mole of gas burned, and hence must be removed as liquid water? d) What is the mole fraction of the remainder gases that exit the heat exchanger?
