A 24-foot uninsulated steam line crosses through a room. The outer diameter of the steam line is 12 in. and the outer surface temperature is 315 °F. The convective heat transfer coefficient for the air is 20 Btu/hr-ft2-°F. The heat transfer rate from the pipe to the room is 2.96x105 Btu/hr. Given: Q=hAAT What is the air temperature in the room (°F)? O 144 O 126 O 119 O132
