The room of a building receives energy from the sun during the day such that the roof temperature becomes too hot to touch at certain times of the day. For a roof-surface temperature of 65°C and an ambient air temperature of 20°C, determine the convective heat transfer 2 coefficient (in W/m¯-K), if the roof makes an angle of 45° with the vertical and has a length of 5 m. Answers: Analysis: convection °C 11 x 10 (scientific notation, 6 decimal places) Nu = 2 h = W/m -K >
