Solved: To supply heated air to a house, a high-efficiency
Chapter 15, Problem 1569(choose chapter or problem)
To supply heated air to a house, a high-efficiency gas furnace burns gaseous propane (C3H8) with a combustion efficiency of 96 percent. Both the fuel and 140 percent theoretical air are supplied to the combustion chamber at 258C and 100 kPa, and the combustion is complete. Because this is a high-efficiency furnace, the product gases are cooled to 258C and 100 kPa before leaving the furnace. To maintain the house at the desired temperature, a heat transfer rate of 31,650 kJ/h is required from the furnace. Determine the volume of water condensed from the product gases per day.
