Question

Pressurized steam at 400 K flows through a long, thin-walled pipe of 0.6 m diameter. The pipe is enclosed in a concrete casing that is of 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 300 K. What is the rate of heat loss per unit length of pipe?

Step 1

Let $d = 0.6 m$ be the diameter of the pipe. Let $L = 1.5 m$ be the side length of the square cross section of the casing. The radius of the pipe is $r = d/2 = 0.3 m$. The area of the square cross section of the casing is $A_c = L^2 = (1.5 m)^2 = 2.25 m^2$. The Show more…

Pressurized steam at 4E0 K flows through a long, thin-walled pipe of 0.6Em diameter. The pipe is enclosed in a concrete casing that is of square cross section and 1.E5 m on a side. The axis of the pipe is centered in the casing, and the outer surfaces of the casing are maintained at 3E0 K. What is the rate of heat loss per unit length of pipe?
