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.
Seeing that natural gas contains approximately 1,030 BTU per cubic foot and propane contains 2,490 BTU per cubic foot, we can easily derive each fuel's cost per BTU and compare their differences in price for more realistic volumes. Let's assume the cost for natural gas is $15.00 per 1,000 cubic feet.
