I've just finished cobbling together a bong & reservoir for my WC and has measured the rate of water loss (thru drift and evaporation) at 0.1 litres every hour w/o any CPU heat. But I expect the evap rate to double to 0.2L/hr when my waterblock's ready. That's 0.016% of the 350gph (1327L/hr) flow rate. The pump itself is rated at 500gph @ 0 head. I'm using a 30cfm, 80mm fan to blow out the moist air. Can anybody give me some input on their bong's evaporation rate?
