To supply heated air to a house, a high-efficiency gas furnaceburns gaseous propane (C3H8) with a combustion efficiency of 96percent. Both the fuel and 40 percent excess air are supplied tothe combustion chamber at 25ï‚°C and 100 kPa, and the combustion iscomplete. Because this is a high-efficiency furnace, the productgases are cooled to 40ï‚°C and 100 kPa before leaving the furnace. Tomaintain the house at the desired temperature, a heat transfer rateof 31,650 kJ/h is required from the furnace. Determine the volumeof water condensed from the product gases per day, inLitre/day.
