The inlet and outlet temperatures of the flowing fluid during a steady state flow process are the same as that of the surroundings. If the changes in kinetic and potential energies are neglected, the maximum power that can be obtained is equal to
- the rate of increase in enthalpy of the flowing fluid
- the rate of decrease in Helmholtz energy of the flowing fluid
- the rate of decrease in Gibbs free energy of the flowing fluid
- the rate of decrease in internal energy of the flowing fluid
