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

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.
