Most people will tell you that ICT is a shortening for âinformation and communications technologyâ â option number one above. Letâs unpack that phrase. So it is âinformation technologyâ or âcommunications technologyâ. It is not âinformationâ or âcommunicationâ standing on its own. âInformationâ or âcommunicationâ has to go with technology â they cannot exist independently. You could shorten information and communications technology to just technology. Option 2
For example, a 24 ft. x 24 ft. garage with an eight-foot ceiling has a volume of 4608 ft.3 (24 * 24 * 8 = 4608) Final Formula. Once you have all the data assembled, multiply them together and divide by 1.6 to find the number of BTUs required to heat your garage. (Insulation * Volume * Temp. Rise)/1.6 = BTU. For example, if your garage was 4608 ft. 3 in volume, your temperature rise was 20Â°F, and your insulation rating was one, it would be: (1 * 4608 * 20)/1.6 = 57,600 BTU
The BTU multiplier in the formula is 500. Because BTUs are measured per hour, the 500 comes from one gallon of water that weighs 8.33 gallons, times 60 minutes in one hour. The second piece of the formula and sometimes the hardest to identify is flow rate in GPM, or the system gallons per minute.
