Pound-Foot/second
A pound-foot per second (lbf·ft/s) is a unit of power representing the rate at which work is done or energy is transferred, equivalent to one pound-force acting through a distance of one foot per second.
History/Origin
The pound-foot per second has been used primarily in engineering contexts within the Imperial system to quantify power, especially in mechanical and automotive applications, though it is less common than other units like horsepower.
Current Use
Today, the pound-foot per second is rarely used; it is mainly referenced in historical data or specific engineering calculations involving Imperial units, with the more standard unit of power being the horsepower or the watt in SI units.
Btu (It)/hour
Btu (IT)/hour (Btu/h) is a unit of power that measures the rate of energy transfer, specifically the amount of British thermal units (IT) transferred per hour.
History/Origin
The Btu (IT) originated from the British thermal unit used in the United States and was standardized for industrial and engineering purposes. The per-hour notation became common in applications requiring power measurement, especially in heating and cooling systems.
Current Use
Btu/h is widely used in heating, ventilation, and air conditioning (HVAC) industries to specify the capacity of heating and cooling equipment, as well as in energy analysis and thermodynamics.
