Dear Hans,<br>
It would not be too much trouble for us to modify Type650 so that
it takes a flow configuration parameter like Type5 and calculates UA
internally but still bypasses hot side fluid around the actual heat
exchanger to maintain the cold side outlet temperature below a set point.
Please feel free to contact me directly if you are interested.<br>
Cheers,<br>

controlling the flow rate on hot side. <br>
