What is the outlet temperature of the steam?

Question

I have 100 ft of unisulated pipe with 400 F steam entering the piping. The pipe is 3 inches in diameter and operates at 150 psi. The pipe thickness is 0.216 inches. Assuming ambient temperature to be 90 F. It is a carbon steel pipe. What is the temperature of the steam at the end of the pipe? Take into account the heat losses.

Answer 1

It seems to me that 100' of pipe will dissipate a lot of heat. The steam temperature at the end will be the saturated steam temperature for 150 psi. Look at your steam table.
