Steam at 350 °C flows through the stainless steel pipe with k=26 W/m.°C. The inner and outer diameters of the stainless steel pipe are 6.0 cm and 7.0 cm, respectively. The pipe is insulated from the outside with a 4.0 cm thick glass wool (k= 0.038 W/m.°C) and then a 3.0 cm thick k=0.25 W/m.K material. The insulated pipe is in the environment at 20 °C. The heat loss from the pipe occurs only by [natural convection+radiation]. Film heat transfer coefficient including the effects of [natural convection+radiation] in the insulated pipe is 30 W/m². is C. Calculate the heat transferred per unit pipe length since the film heat transfer coefficient defined according to the inner area of the pipe is 110 W/m².°C.
