A copper pipe (k = 400 W/m-K) has an internal diameter of 10 cm and an external diameter of 12 cm. Saturated steam (h 10,000 W/m²K) flows inside the pipe at 110°C. The pipe is located in a space at 30°C and the heat transfer coefficient on its outer surface is estimated to be 15 W/m²K. a. Determine the heat loss from the uninsulated pipe. b. Determine the heat loss from and insulated pipe if the insulation available to reduce heat loss is 5 cm thick and its conductivity is 0.20 W/m-K.
