Which of these is a disadvantage of the Navier-Stokes equations?
(a) No independent-equation for pressure
(b) No independent-equation for temperature
(c) No equation to find the density
(d) No equation to find the velocity
This question was posed to me in my homework.
My enquiry is from Incompressible Flows in chapter Incompressible Flows & Compressible Flows of Computational Fluid Dynamics
