The form of quasigasdynamic (QGD) equations oЬtained Ьу the momentary averaging of the model kinetic equation is presented. Based on the representation of the QGD equations in the form of differential conservation laws and the separation of the dissipative terms in the Navier-Stokes form, an estimation formula for the volume viscosity coefficient is oЬtained. The formula derived is similar to the known volume viscosity expression associated with the rotational nonequilibrium.
