Dear Sirs
Working on Designing reboiler and condenser with Graphite Block type heat exchanger
Block type heat exchanger is cross flow heat exchanger.Holes are drilled for different fluids in a block.i.e. All heat phenomena can be considered tube side for both fluids.
My question is how to calculate Overall Heat transfer coefficient for block type heat exchanger or by which formula.Formula for Shell and tube heat exchanger cannot be used.
I would like to correlate with Shell and tube heat exchanger by using heat transfer coefficients tube side for both sides.By this way one can use standard correlation for shell and tube heat exchangers
Request to give me either formula or better if excel spread sheet or literature
Thanks in Advance
Regards
Samir
