Octane is burned in an incinerator with the proportions shown below. The fuel enters the device at 537R and the air enters at 560R. The hot gases leave the device at 1060R. The mass flow rate of fuel into the system is 20.0 lbm/hr. All flows are at a pressure of 14.5 psia. Determine a. the rate of heat transfer from the device per kmol of fuel (Btu/lbmolOctane) b. the density and volumetric flow rate of air entering
