Question:

The inner wall of a rocket motor combustion chamber receives 50,000 Btu/(h ft2) by radiation from a gas at 5000? F. The convective heat transfer coefficient between the gas and the wall is 20 Btu/(h ft2 ?F). If the inner wall of the combustion chamber is at a temperature of 1000? F, determine the total thermal resistance of a unit area of the wall in (h ft2 ?F)/Btu and the heat flux. Also draw the thermal circuit.GIVENWall of a rocket motor combustion chamberRadiation to inner surface (qr/A) = 50,000 Btu/(h ft2)Temperature of gas in chamber (Tg) = 5000?FConvective heat transfer coefficient on inner wall (hc) = 20 Btu/(h ft2 ?F)Temperature of inner wall (Tw) = 1000?FASSUMPTIONSOne dimensional heat transfer through the walls of the combustion chamberSteady state heatflow
