Convector sizing

[RussellC]

I need to size a convector/radiator that has not airflow (no direct fan). BTUH is known, material stainless steel 316, 11 gpm, and the convector should be roughly 36 inches wide and 24 inches tall. ANy help with sizing this would be helpfull.

Hi Russel,
What other sizes do you need apart from 36" wide and 24" high? If you need inlet / outlet nozzle sizes, you need to know the fluid you are cooling / heating (water, oil, refrigerant,...), specific heat, air wet bulb temperature (America, Europe, Africa...), wind or stagnant air, etc...For 11 gpm water, you'll be loking perhaps for 1"-1 1/2" NPS nozzles, depending on temperature also, but that's not engineering, is only a quick estimate on your information. Sorry, but you have to provide a lot more information to get a specific answer.
Cheers,

well essentially what we are trying to do is cool-down a high pressure pump during part-load conditions. The unloader so to speak is approx 1/2 inch this is that part that relieves pressure from pump during part load. this gets recirced to pump inlet. The pump is rated at 11.3 gpm and 5600 watts. This essentially converts to 18K BTUH which i rounded to 20K BTUH. We are trying to cool this down approximately 10 degrees by use of a convector type application with approx 80 deg f space temp. Im not sure what my actual load is--the watts to BTUH number of 18K or would it be gpm * 500 * TD which would bring me way up to 55K. thanks for the reply.
