Thermal Power heat usedtime requiredPOWEREnergy, Work, and PowerCP-05 Page 8Rev. 0POWERPower is a measure of the rate at which energy is used. Thermal power is the termused to refer to the transfer of heat. Mechanical power is the term used to describewhen work is being done.EO 1.1DEFINE the following terms:e.PowerEO 1.2STATE the mathematical expression for:d.Power EO 1.3For a mechanical system, CALCULATE energy, work, andpower.PowerPoweris defined as the amount of energy used per unit time or rate of doing work. It has the unitsof watt, Btu, horsepower, or ft-lbf/sec.ThermalPowerThermal poweris the measure of thermal energy used per unit time. It is the rate of heat transferor heat flow rate. Examples of thermal power units are British Thermal Units (Btu) or kilowatts(Kw). Thermal power is calculated basically by the mathematical expression of:Thermal energy and calculations of thermal power will be covered in more detail in the FundamentalsManual for Heat Transfer, Fluid Flow, and Thermodynamics.
