2. (11 marks total) Ethanol (CHOH) burns in a domestic furnace at a pressure of 101.3 kPa according to the following stoichiometric equation: CHOH + 4.0 (O+3.76 N) 2.0 CO+ 3.0 HO + 1.0 O + 15.04 N The fuel and air enter the furnace at 25C and the products leave at 40C. Determine: (a) (2 marks) the dew point of the products; (b) (4 marks) the amount of water condensed from the products and the product composition after condensation, all in kmol/kmol fuel; (c) (5 marks) the heat transfer from the furnace in MJ/kmol fuel. Data: Ethanol: molecular mass M = 46 kg/kmol, higher heating value HHV = 31.6 MJ/kg. Product Enthalpies: CO HO O N Ah at 40C (kJ/kmol) 579 504 441 433 hfg (kJ/kmol) 43 961
