Mass flow rate formula derivation
WebCompressible Flow 1. Mach Number: 2. Compressibility becomes important for High Speed Flows where M > 0.3 • M < 0.3 – Subsonic & incompressible • 0.3 < 0.8 – Subsonic & compressible • 0.8 < 1.2 – transonic flow – shock waves appear mixed subsonic and sonic flow regime • 1.2 < 3.0 - Supersonic – shock waves are present Web31 de oct. de 2024 · Figure 2: Fluid flow in a pipe that is constricted using an orifice plate. Source: Mbeychok/CC [SA][3.0] Due to the steady-flow nature of the fluid flow, the conservation of mass principle requires that the total rate of mass entering through the inlet of this pipe equals the total rate of mass exiting through the outlet.
