Sous Vide Steak Safety. The FDA states that beef is safe when it is held at 130Â°F for over 112 minutes, or 140Â°F for over 12 minutes. This is very easy to do with sous vide and the main reason we recommend cooking most beef cuts medium-rare since beef is most tender at that temperature.
btu per pound * pounds per gallon   OK, it sounds as if you know the value of fuel in oil btu per pound.Now find out how much a gallon of fuel oil weighs and multiply the bâ¦tu value x that weight in pounds and that is the value per gallon. Or simply, diesel fuel is #2 fuel oil which contains 140,000 btu per gallon.
Oil burns at 130,000 BTU/Gallon. You can determine the amount of burn time you have by dividing 130,000 by the input capacity of the boiler and multiplying that number times the (approximate) gallons of oil in the tank. Example: A 100,000 *input* btu boiler will burn 260 hours on 200 gallons of fuel.
