Question details

PRINTER VERSION « nACK Supplemental Problem 1.007 rectangular forced air heating duct is suspended from the celing of a basement whose air and walls are at a temperature of T.-T--se ts cross section is 300 mm x 225 mm. The duct is 15 m on an 1) For an uninsulated duct whose average surface temperature is so°c, estimate the rate of heat loss from the duct. pproximately 0.5 and 4 W/m2.K, respectively. The surface emissivity and convection of 4 m/s and the heat loss corresponds to the result of part (1), what is the outlet temperature? The density and pecific heat of the air may be assumed to be ρ-1.10 kg/m3 and c,-1008 rkg-K. respectively. Step 1 Your answer is incorrect. Try again. ind the rate of heat loss from the duct by convection, in w. he tolerance is +/-296 By accessing this Question Assistance, you will learn while you earn points based on the Point Potential Policy set by your instructor
