Natural gas is used in a home heating system and burns in the combustion chamber according to the following equation (0.90 CH4 + 0.05 C2H6 + 0.05 Nz) + 2.2 (02 + 3.76 NI N CO2 + 1.95 H20 + 0.225 02 + 8.322 N2 PDF to The air-natural gas mixture enters the system at 25C and exits at 40C. The pressure is 101.3 kPa. a) Determine the amount of condensed water in kmol/kmol of fuel (7 points) b) Calculate the heat loss from the combustion chamber in kJ/kmol of fuel
