How to calculate time to heat a volume of air

Web19 mrt. 2012 · Rob, The heat capacity of air at sea level is, on average, 0.018 Btu per cu. ft. per degree F. So the infiltration heat loss calculation is: [delta-T] x [ACH (actual)] x [volume] x 0.018, where ACH (actual) is the actual … Web12 jun. 2024 · To heat a given volume of air by a given amount requires energy. It would make sense if you specified a period of time for that level of power. Aug 27, 2013 #3 sromag 10 0 Thanks for the reply. As for time period, say 10 minutes - 600 seconds.

Web13 mrt. 2004 · The specific heat at those conditions is about 0.24 BTU/lbm/degF. So, 9100 BTU / (2060 lbm * 0.24 BTU/lbm/degF) = 18 degF temperature rise if there is zero ventilation. It's linear with how much air is in the room, and if there is enough ventilation to equal one air change per hour the effect will be almost totally canceled out within one hour. WebThere are two kinds of enthalpy of combustion, called high (er) and low (er) heat (ing) value, depending on how much the products are allowed to cool and whether compounds like H. 2O are allowed to condense. The high heat values are conventionally measured with a bomb calorimeter. Low heat values are calculated from high heat value test data.
