I have a simple single pass two pipe heat exchanger that uses staturated Steam (250 F) to heat a pressurized gas from 40 F to 120 F. The inner pipe carries the steam. Inner pipe has smooth wall on its inside surface and has fins on its outsde surface. The pressurized gas flows on the shell side (cross flow) and contacts the fins. I want to change the heating fluid from steam to water/glycol mix (180 F-190F). How do I calculate how affective the heat exchanger is with the new fluid? Reference texts or publications?
