spot on, thanks guys, Wish we could all use one set of units....

exactly, The one calculation ends up with 5.85KW and the later ends up with 56.9KW, what am i missing....

then i must be missing something. When I use a example thus. Flow rate of 20GPM Change in temp 20deg F Thermal duty value of 500 (water) change in temp x thermal duty x GPM 20 x 500 x 20 = 20000 btu's = 5.85Kw using the other formula and using SI units 20gpm = 75.7 litres/min 20 deg F =...

I have to calculate the approximate heat tranfer in KW for a tube heat exchanger in KW.(for a hydraulic power pack) I have the formula for calculating it in BTU's Q= change in temp x thermal duty value8 GPM The formula i thought should work was Q= change in temp x specific heat capacity x flow...
