Entropy

Entropy changes, balances, and isentropic efficiencies.

Entropy quantifies the irreversibility of processes. This module closes the course with entropy balances and isentropic efficiencies.

What you will learn

  • Calculate entropy changes in pure substances and ideal gases.
  • Set up entropy balances in closed systems and control volumes.
  • Evaluate the isentropic efficiencies of turbines, compressors, and nozzles.

Study tip

Relate every result back to the Second Law: the entropy generated is never negative, and that criterion tells you whether a process is possible.
