Please do not copy answer from previous asked question, as I believe it is wrong.

5-42 Ethane (CH) at 77F is burned at a rate of 0.16 lbm/min in the combustion chamber of a boiler with 20 percent excess air that also enters at 77F. The products leave the boiler at 323F. Assuming combustion is complete, determine the rate of energy lost with the exhaust gases, in Btu/h, and percent exhaust loss based on the higher heating value of the fuel. Use the average value of specific heat for the exhaust gases
