How is heat rate calculated
WebThe mass flow rate can be calculated by heat transfer equation ΔQ = m° Cp ΔT. It is also measured by using a flow measuring instrument. If we have values of the heat transfer rate (kW), specific heat at constant pressure (kJ/kg K) and the temperature difference in K. The mass flow rate is generally measured rather than a calculation from heat. Web7 aug. 2024 · For example, if the boiler runs for 1,800 seconds, dividing 12,558,000 by 1,800 gives 6,977, or a little under 7,000. This is the heat input rate, measured in joules per …
