Step 3: Prepare the Spreadsheet. In this tutorial, we will create a very simple macro to change the color, size and boldness of text. In your spreadsheet, type in some text in any of the cells. We will later record a macro to change the formatting of this text.
The average cooling capacity of a dorm fridge is somewhere around 150 BTU/hr, that is, it is capable of moving 150 BTUs of heat in 1 hour, regardless of how efficient (or inefficient) it is in terms of energy usage.
Most frost-free refrigerators have a timer that runs them for 6 hours, then defrosts them for 30-35 minutes. This means, at the the upper limit a refrigerator might run 24 hours out of every 26 hours, or an equivalent of 22.1 hours per day.epends on the size of the burner, if the unit is 5000 btu's ,(probably much smaller), but it makes the math easy that would run a fridge (full throttle) for 20 hours. The fl â¦ ame cycles, so it won't use that non stop.
