Steam at 280C flows in a stainless steel pipe k = 15 W/m.K whose inner and outer diameter are 5cm and 5.5cm, respectively. The pipe covered with 3cm glass wool insulation k = 0.038 W/m.K. Heat is lost to the surroundings at 5C by natural convection and radiation, with a combined natural convection and radiation heat transfer coefficient of 22W/m2.K. Taking the heat transfer coefficient inside the pipe to be 80W/m2.K, determine the rate of heat loss from the steam per unit length of the pipe. Also determine the temperature drop across the pipe shell and the insulation
