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.
Well that is the key to knowing your consumption! A gallon of propane contains roughly 90,000 btu's. So, just to keep it simple if you have a 90,000 btu furnace it will burn 1 gallon for every hour it operates. If it runs 30 minutes out of every hour, it will burn 1 gallon in 2 hours.enerally speaking for every dollar you would spend heating a home electrically, you will spend roughly $0.80 to do the same job with oil, $0.70 to do it with propane, and about $0.55 to heat with natural gas. This varies somewhat by region but that is average.
