Which of these differences occur in the momentum equation of the compressible flows when compared to that of the incompressible flows?

Which of these differences occur in the momentum equation of the compressible flows when compared to that of the incompressible flows? Correct Answer Bulk viscosity

In the incompressible flows, the bulk viscosity term is omitted as the density is constant. But, in the compressible flows, this cannot be omitted. This is an additional term in the momentum equation of the compressible flows.
