Question

Equations of state provide the linkage between ___________ and ____________

(a) Conservative, non-conservative equation

(b) Eulerian, Lagrangian equations

(c) Energy equation, mass and momentum equations

(d) Differential, Integral equations

I got this question by my school teacher while I was bunking the class.

The origin of the question is Equations of State in chapter Governing Equations of Fluid Dynamics of Computational Fluid Dynamics

Answer 1

Right choice is (c) Energy equation, mass and momentum equations

For explanation I would say: Equations of the state provide the linkage of Energy equation with mass and momentum equations. They give the thermodynamic properties in terms of the state variables.
