respectively. The pipe is covered with 4.5-cm-thick glass wool insulation [k=0.042 W/(m. °C)]. Heat is lost to the
surroundings at 10 °C by natural convection and radiation, with a combined natural convection and radiation heat transfer
coefficient of 22 W/(m2.°C). Taking the heat transfer coefficient inside the pipe to be 86 W/(m². C), 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.
