Pound-Foot/minute
Pound-foot per minute (lbf·ft/min) is a unit of power representing the rate at which work is done or energy is transferred, specifically the amount of work in pound-feet performed per minute.
History/Origin
The pound-foot per minute has been used historically in engineering and mechanical contexts to measure power, especially in systems where imperial units are prevalent. It is derived from the foot-pound unit of work, divided by time in minutes, aligning with traditional British engineering practices.
Current Use
Today, pound-foot per minute is primarily used in specific engineering fields, such as mechanical and automotive industries, to measure torque-related power outputs, though it is less common than SI units like watts or horsepower.
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.
