2-2. (25%) Consider a cylinder pipe of outer radius r1 whose outer surface temperature is T1 . The pipe is now insulated with a material whose thermal conductivity is k and outer radius is r2. Heat is lost from the pipe to the surrounding medium at temperature Ts , with a convection heat transfer coefficient h . Please use the concept of thermal resistance to obtain the expressions of the heat transfer rate q and the critical radius of insulation by differentiating q with respect to r2 . ()

5. (25%) We may define the wind-chill factor in weather reporting as the calm-air temperature that causes the same heat flux as a given windy day. Suppose that human skin is 4.0 mm thick (k =0.37 ), with no heat generation and maintained on its inside surface at . Let convection heat transfer coefficient h be 15 on a calm day and be 55 on a windy day. If air temperature Ta is ,(a) What are the surface temperature Ts and heat flux loss on a calm day?(b) Repeat (a) for a windy day.(c) What is the wind-chill factor for these windy conditions? (i.e. find Ts and Taw)()
