Q2/ Consider a steam pipe of length L= 5.5 m, inner radius r1 = 4 cm., outer radius r2 = 2.5 cm., and themal conductivity k = 7.2 W/m °C Steam is flowing through the pipe at an average temperature of 25 °C, and the average convection heat transfer coefficient on the inner surface is given to be h = 20 W/m? . °C. If the average temperature on the outer surfaces of the pipe is T2 = 16 °C. (a) express the differential equation and the boundary conditions for steady one dimensional heat conduction through the pipe, (b) obtain a relation for the variation of temperature in the pipe by solving the differential equation, and (c) evaluate the rate of heat loss from the steam through the pipe
