WebFeb 15, 2008 · It is actually saying that 15,000 Btu/hour equals delta T of 10F at 3 gallons per minute. To estimate evaporation rate needed to reject heat for per ton of refrigeration, I would do: (15000 btu per hour) / (2260 kJ/litre) = 0.030 US gallons per minute or 0.1167 litres per minute or 0.168 m^3 per day WebSep 14, 2015 · Depends on the BTU output of the burner, and a few other variables. Looks like that's a Dark Star? If so, that's comparable to the SQ14 I used to use. With that, it would take me about 45-50 minutes to get 6 or 7 gallons from room temp to a boil, and about 20-25 to go from mash temps to a boil. YMMV, but that's a rough estimate.

Heating oil. 1 gallon = 138,500 BTU. Propane. 1 gallon = 91,452 BTU. The higher the BTU per unit of fuel, the more efficiently you can heat a given space. Translation: You get a lot more oomph from a gallon of propane or heating oil than you do from a cubic foot ... WebAnnually, an estimated 495,000 cubic kilometer of water evaporates into the atmosphere. Approximately 990 cubic kilometer or 261,530 billion gallons are lost through evaporation of fresh water reservoir. Even preventing a fraction of this evaporative loss would permit to replenish aquifers, lakes and rivers. iaa weather
