Consider a steam pipe of length L = 30 ft, inner radius r_{1} = 2 in, outer radius r_{2} = 2.4 in, and thermal conductivity k = 7.2 Btu/h·ft·°F. Steam is flowing through the pipe at an average temperature of 300°F, and the average convection heat transfer coefficient on the inner surface is given to be h = 12.5 Btu/h·ft^{2}·°F. If the average temperature on the outer surfaces of the pipe is T_{2} = 175°F,
(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.
