Question
A 2 inch Schedule 40 pipe carrying hot fluid coated with insulation 2 cm thick. The conductivity of this insulation k = 0.06 W / m.K. This insulation is useful for reducing heat. The inner diameter and outer diameter of the pipe are 5.25 cm and 6.03 cm, respectively. The inner surface temperature of the pipe is 150 ° C and the outer surface temperature of the insulation is 25 ° C. Pipe conductivity = 43 W / m.K. Calculate: a. Heat transfer rate per m pipe length b. Pipe outer surface temperature
