Applied thermodynamics applied thermodynamics is the science of the relationship between heat, work, and systems that analyze energy processes. The energy processes that convert heat energy from available sources such as chemical fuels into mechanical work are the major concern of this science

Black body radiation black body radiation curves

Black body radiation

Black body radiation blackbody radiation or cavity radiation refers to an object or system which absorbs all radiation incident upon it and re-radiates energy which is characteristic of this radiating system only, not dependent upon the type of radiation which is incident upon it

Boiler water a boiler is a closed vessel in which water under pressure is transformed into steam by the application of heat. In the boiler furnace, the chemical energy in the fuel is converted into heat, and it is the function of the boiler to transfer this heat to the contained water in the most efficient manner

Boyle's Law Boyle's Law: the pressure and volume of a constant quantity of gas at constant temperature

Cooling systems cooling water systems are either nonevaporative or evaporative. Nonevaporative systems include once-through cooling and closed loop systems. Evaporative cooling systems include open recirculating systems in which heat rejection is accomplished in cooling towers, evaporative condensers, spray ponds or cooling lakes
