Steam at 320°C flows in a stainless steel pipe (k =15 W/m·K) whose inner and outer diameters are 5 cm and5.5 cm, respectively. The pipe is covered with 3-cm-thickglass wool insulation (k = 0.038 W/m·K). Heat is lost to thesurroundings at 5°C by natural convection and radiation, witha combined natural convection and radiation heat transfercoefficient of 15 W/m2·K. Taking the heat transfer coefficientinside the pipe to be 80 W/m2·K, determine the rate of heatloss from the steam per unit length of the pipe. Also determinethe temperature drops across the pipe shell and the insulation.

Steam at 320°C flows in a stainless steel pipe (k =
15 W/m·K) whose inner and outer diameters are 5 cm and
5.5 cm, respectively. The pipe is covered with 3-cm-thick
glass wool insulation (k = 0.038 W/m·K). Heat is lost to the
surroundings at 5°C by natural
a combined natural convection and radiation heat transfer
coefficient of 15 W/m2·K. Taking the heat transfer coefficient
inside the pipe to be 80 W/m2·K, determine the rate of heat
loss from the steam per unit length of the pipe. Also determine
the temperature drops across the pipe shell and the insulation.
