Steam Heating Process - Load Calculating

Calculating the Amount of Steam. If we know the heat transfer rate - the amount of steam can be calculated: ms = P / he (4) where. ms = mass of steam (kg/s) P = calculated heat transfer (kW) he = evaporation energy of the steam (kJ/kg) The evaporation energy at different steam pressures can be found in the Steam Table with SI Units or in the ...

Exergy Balance Equation - an overview | ScienceDirect Topics

Exergy transfer between the system and surroundings can be done by work, mass transfer, and heat transfer. The exergy due to work transfer (Ex W) is by definition equal to the work: Ex W =W.However, if the system impinges against a moving boundary then the exergy must be diminished accordingly, thence Ex W =W–P 0 (V–V 0).The exergy associated to mass transfer …
