WebMay 13, 2024 · Considering the mass flow rate equation, it appears that for a given area and a fixed density, we could increase the mass flow rate indefinitely by simply increasing the velocity. In real fluids, however, the density does not remain fixed as the velocity increases because of compressibility effects. We have to account for the change in … WebMay 13, 2024 · a = sqrt (gam * p / r) = sqrt (gam * R * T) where R is the gas constant from the equations of state.
