Ahorizontal steam pipe (d i = 7.8 cm, d 0 = 8.9 cm) carries saturated steam at 200.5 0 c. a 2 cm thick insulation ( k = 0.05 w/m-k) is installed to reduce heat loss to the ambient air at 25 0 c. neglecting internal convection resistance and radiation loss from the external surface, calculate the rate of heat loss per meter length of the pipe.
