Question

Among the unknowns of a flow field, some of the properties are given below. Which set contains only thermodynamic properties?

(a) Density, pressure, specific internal energy, temperature

(b) Density, velocity, specific internal energy, temperature

(c) Velocity, pressure, specific internal energy, temperature

(d) Density, pressure, specific internal energy, Velocity

I have been asked this question in an international level competition.

I want to ask this question from Equations of State topic in division Governing Equations of Fluid Dynamics of Computational Fluid Dynamics

Answer 1

The correct choice is (a) Density, pressure, specific internal energy, temperature

Explanation: Velocity is a property completely related to fluid flow. The other properties – density, pressure, specific internal energy and temperature are thermodynamic.
