Question - Is There A Quick Rule-of-thumb To Estimate A Gas Side Heat-transfer Rate Inside The Tubes Of A Shell And Tube Heat Exchanger?
Answer -
If you need to estimate a gas heat transfer rate or see if a program is getting a reasonable gas rate, use the following: h = 75 X Sq. Root(Op. pressure/100) The operating pressure is expressed as absolute. This is for inside the tubes. The rate will be lower for the shell side or if there is more than one exchanger.
