Solution:
QUESTION: 6

Isentropic flow is always
1. zero increase in entropy flow.
3. Frictionless reversible flow.

Solution:

In fluid dynamics, an isentropic flow is a fluid flow that is both adiabatic and reversible. That is, no heat is added to the flow, and no energy transformations occur due to friction or dissipative effects. For an isentropic flow, entropy density can vary between different streamlines.
