A thick walled stainless steel pipe of inside and outer radii as 20 mm and 40 mm, respectively is heated electrically to provide a uniform heat generation rate of 106 W/ m². The outer surface of the pipe is insulated. The water flows through the pipe at a rate of 0.1 kg/s.

 (a) If water inlet temperature is 20°C and desired outlet temperature is 40°C, what is the required pipe length ?

(b) What are the location and value of the maximum pipe temperature ?
