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.
Calorie (Th)/hour
Calorie per hour (cal(th)/h) is a unit of power representing the amount of heat energy in calories transferred or used per hour.
History/Origin
The calorie, originally defined as the amount of heat needed to raise the temperature of 1 gram of water by 1°C, has been used in various contexts including nutrition and physics. The 'th' denotes the thermochemical calorie, an older standard. The unit cal(th)/h has been used historically in thermodynamics and heat transfer measurements.
Current Use
Today, cal(th)/h is rarely used in modern scientific contexts, having been largely replaced by SI units like watts. However, it may still appear in legacy systems or specialized fields involving heat transfer calculations.
