Superheated steam at an average temperature of 200°c is transported through a steel pipe (k=50 w/m-k, do = 8 cm, di = 6 cm and l = 20 m). the pipe is insulated with a 4 cm thick gypsum plaster (k=0.5 w/m-k). the insulated pipe is placed horizontally in a warehouse where the average temperature is 10°c. the steam and air side heat transfer coefficients are 800 and 200 w/m²- k respectively. calculate a) rate of heat transfer from the superheated steam b) outside surface temperature of the insulation.
