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.
Energy consumption and output is measured in British Thermal Units regardless of energy source. BTUs are convenient because each energy is measured differently: LP gases are measured in gallons, natural gas is measured in cubic feet, electricity is measured in kWh, etc.The same goes for price (dollars per gallon, per thousand cubic feet, per kWh).his is easily converted into gallons: one only needs to divide the number of BTUs by 91,574 (number of BTUs per gallon), so a 200,000 BTU/hr furnace will use around 2.2 gallons of propane each hour it is running (this seems like a lot and is only true if the appliance is running at full power all the time).
