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