The equation describes the conservation of mass and momentum over time within a system. The first term represents the total rate of change of mass or momentum over time. The second term gives the local rate of change within the system. The third term accounts for the flux of mass or momentum across the boundaries of the system due to convection.

1. What is the physical meaning of each term in the below equation? DM_sys/Dt = partial
differential/partial differential t integral rho*d Forall + CV integral rho*V*n*dA CS What is the
physical meaning of each term in the below equation? DB_sys/Dt [D/Dt integral V*rho*d
Forall] = partial differential/partial differential t integral V*rho*d Forall + CV integral
V*rho*V*n*dA Volumetric Dilatation Rate =
Solution
12)first term is thetotal mass rate of change with time with velocity flux ( total derivative D/Dt =
(d/dt + v.d/dv)M)
second term is due to the mass rate of change only
the third is the flux of mass thru the boundaries
13) same except this is momentum flux, D/Dt is the total derivative the other terms are the terms
in the total derivative
