ugghh ... I cann't talk on the phone while doing math in my head, and writing this. The end results are about right (which I've done dozens of times) the in intermediates are jumbled. If there is an error here let me know. 17.5KW/hr is about 15 million calories per hour, or about 4 kilocalories/min. If we allow a 4C rise in coolant from input to output of the processor stack, then we need 1 kilogram/min of water, which is about 132lbs/min, or rougly 16 gallons/min of water as a coolant at room temps. If chilled water is available, it takes considerably less. from units: You have: kilowatt You want: calories/hour * 859845.23 / 1.163e-06 then 17.5 * 859845.23/60/1000 = 251 kilocalories/min a 4C rise would then be 62.75 kilogram/min of water, which is about 62.75*2.2 = 138.05lbs/min or 17 gallons/min _______________________________________________ Hardware mailing list Hardware-Ra3b/QYEcJ3d140v2zMXi0fjHoOT/h/[email protected] http://lists.distributed.net/mailman/listinfo/hardware
