  2. Ton of refrigeration - Wikipedia

    en.wikipedia.org/wiki/Ton_of_refrigeration

    12,000.00 Btu IT /h 2,593.90 ft⋅lbf/s A ton of refrigeration ( TR or TOR ), also called a refrigeration ton ( RT ), is a unit of power used in some countries (especially in North America) to describe the heat-extraction capacity of refrigeration and air conditioning equipment.

  3. British thermal unit - Wikipedia

    en.wikipedia.org/wiki/British_thermal_unit

    Btu per hour (Btu/h) is sometimes used in North America and the United Kingdom - the latter for air conditioning mainly, though "Btu/h" is sometimes abbreviated to just "Btu". [18] MBH—thousands of Btu per hour—is also common. [19] 1 W is approximately 3.412142 Btu/h [20] 1,000 Btu/h is approximately 0.2931 kW; 1 hp is approximately 2,544 Btu/h

  4. Specific heat capacity - Wikipedia

    en.wikipedia.org/wiki/Specific_heat_capacity

    The BTU was originally defined so that the average specific heat capacity of water would be 1 BTU/lb⋅°F. [19] Note the value's similarity to that of the calorie - 4187 J/kg⋅°C ≈ 4184 J/kg⋅°C (~.07%) - as they are essentially measuring the same energy, using water as a basis reference, scaled to their systems' respective lbs and °F ...

  5. Energy content of biofuel - Wikipedia

    en.wikipedia.org/wiki/Energy_content_of_biofuel

    The table below includes entries for popular substances already used for their energy, or being discussed for such use. The second column shows specific energy, the energy content in megajoules per unit of mass in kilograms, useful in understanding the energy that can be extracted from the fuel.

  6. Talk:British thermal unit - Wikipedia

    en.wikipedia.org/wiki/Talk:British_thermal_unit

    As of right now the unit conversion template gives different values for 1,000 British thermal units per pound (2,300 kJ/kg) and 1,000 British thermal units per pound (2,300 kJ/kg) while describing both units as "British Thermal Units". Is there some method to the madness or does the code need fixing?

  8. Gasoline gallon equivalent - Wikipedia

    en.wikipedia.org/wiki/Gasoline_gallon_equivalent

    The energy content of ethanol is 76,100 BTU/US gal (5.89 kilowatt-hours per litre), compared to 114,100 BTU/US gal (8.83 kWh/L) for gasoline. (see chart above) A flex-fuel vehicle will experience about 76% of the fuel mileage MPG when using E85 (85% ethanol) products as compared to 100% gasoline. Simple calculations of the BTU values of the ...

    en.wikipedia.org/wiki/Hazelnut

    Cracked hazelnut shell displaying the edible seed Hazelnut tree, Turkey. A hazelnut cob is roughly spherical to oval, about 15–25 millimetres (5 ⁄ 8 –1 inch) long and 10–15 mm (3 ⁄ 8 – 5 ⁄ 8 in) in diameter, with an outer fibrous husk surrounding a smooth shell, while a filbert is more elongated, being about twice as long as its diameter.
