Pressurized steam at 460k flows through a long, thin walled pipe of 0.5m diameter. the pipe is enclosed in a concrete casting that is of a square cross section and 1.5 m on a side. the axis of the pipe is centered in the casing, and the outer surfaces of the casing are maintained at 350k. determine the heat loss per unit length of pipe.
