Hello – I am researching ways to account for localized effects of elevation and humidity in calculations of evaporative waste heat disposal. Specifically I want to understand the inner math of the heat/mass transfer calculations in order to imbed an APPROXIMATE shortcut in a simplified model of evaporative water consumption for cooling towers.

I'm not looking to create complete psychrometric substitutions at reduced pressures that result from increasing elevation (and localized absolute humidity trends), but rather to understand quantitatively how to adjust a model of sea-level performance …… unless perhaps an explanation of the details gives me such a clear view that I can't avoid a basic psychrometric approach. My fixation on simplicity results from time and budget constraints, not so much from laziness (though that could be a consideration, too ….. ;-) )

Thanks for any help – please respond to my e-mail address at martin.vorum@nrel.gov

Hi Martin, I think the psychrometrics routines take barometer reading as a parameter; so there is no trouble to produce results at any atmospheric pressure level. I need to go back and check the program to see if this is true, though…
