Why does metal get cold faster than other materials

Hot water boils faster than cold water because it is closer in temperature to the boiling point. The boiling point of water is 100 o C. If we had hot water at 90 o C and cold water at 20 o C, then

What is a boiler horsepower (BHP), a measurement

Boiler horsepower (BHP) is an obsolete non-metric measurement unit of power. Nevertheless, BHP is still used to measure boiler output in industrial boiler engineering in North America. One Boiler Horsepower (1BHP) is equal to a bolier thermal output of 33 475 BTU/h (British Thermal Units per Hour) or 9.81055407 kW (Kilowatts).
