Re: Cooling water pipe network analysis

Mr Goel:

you might consider an initial appraisal of which are the "critical" exchangers. typically just a few exchangers have low enough velocities to cause scaling and fouling problems. and these problems in turn lead to inadequate heat transfer. often minor piping adjustments or addition of a "boost pump" are enough to address this issue.

alternatively, modeling the distribution system can be done using one of several available programs. often the result is a bit inaccurate and should be confirmed using "strap-on" ultrasonic transmitters at several points in the system. once this analysis is performed, one can re-size, replace, or supplement the circulation pumps.

one problem often encountered with up-sizing the pumps is that older distribution systems often have transite piping located underground. this piping often fails under the additional pressures seen with new pumps.

hope this helps.
