Question
Consider a steam pipe of length L
2 in., outer radius
r2 = 2.4 in., and thermal conductivity k = 7.2 Btu/h - ft - F. Steam is flowing through
the pipe at an average temperature of 250°F, and the average convection heat
transfer coefficient on the inner surface is given to be h = 12.5 Btu/h - ft? - F. If the
15 ft, inner radius ri =
average temperature on the outer surfaces of the pipe is T2 = 160°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. Answer: (c) 16,800 Btu/h
