Flow vs pressure equation

WebGas will always flow where there is a difference in pressure Δp = (p 1 – p 2) > 0. The intensity of the gas flow, i.e. the quantity of gas flowing over a period of time, rises with the pressure differential. In the case of viscous flow, however, this will be the case only until the flow velocity, which also rises, reaches the speed of sound. WebMay 13, 2024 · If we start with the mass flow rate equation given above and use the isentropic flow relations and the equation of state , we can derive a compressible form of the mass flow rate equation. We begin …
