Is there any rule for setting cooling water velocity flowing inside the tubes to get better performance of exchanger?
Have an insight or suggestion?

Re: How do you get better performance from a heat exchanger?21 July 2010 at 1:29pmSince water flow through an exchanger is not frequently a limiting resistance, I would suggest that 3-5 ft/sec should be more than adequate for most circumstances. If, however, the wall temperature is above 60C then there is likely carbonate scale fouling.
