Equation
Arrow pointing to the entropy generation term.
Rate at which entropy is generated within the system per unit mass of flowing fluid.
Red arrow pointing at the entropy transfer term.
Net rate at which entropy is transferred to the system in the form of heat transfer, per unit mass of flowing fluid.
Gold arrow pointing at the entropy change term.
Entropy change of the system per unit mass of flowing fluid.
Dividing by Mass flow rate, m dot. :
