Question

Fluid velocity is very high. Will thermodynamic equilibrium be applicable to fluid flows?

(a) Yes, the external conditions help them stay in thermodynamic equilibrium

(b) No, their flow properties change abruptly

(c) No, they are influenced by external conditions

(d) Yes, the fluid can thermodynamically adjust itself quickly to be in thermodynamic equilibrium

Answer 1

The correct answer is (d) Yes, the fluid can thermodynamically adjust itself quickly to be in thermodynamic equilibrium

To explain: The velocity of fluid flow is very high. This may affect their thermodynamic equilibrium. But, the particles are small enough to thermodynamically adjust themselves to equilibrium so quickly.
