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 (Th)/hour
Btu (th)/hour is a unit of power that measures the rate of energy transfer, specifically the amount of thermal energy in British thermal units (Btu) delivered or consumed per hour.
History/Origin
The Btu (th)/hour originated from the British thermal unit (Btu), a traditional unit of heat energy, and has been used primarily in the heating and energy industries to quantify thermal power rates. Its usage dates back to the early 20th century as a standard measure in thermal energy calculations.
Current Use
Today, Btu (th)/hour is used mainly in the heating, ventilation, and air conditioning (HVAC) industry, as well as in energy consumption and efficiency assessments, to specify thermal power rates of equipment and systems.
