Air Flow Sensor

Flow rate sensor of Air

 Description The Air Flow Sensor component monitors the mass flow rate and other properties. This component assumes an ideal situation; no energy is lost between the ports.
 Equations Monitor definitions: $\mathrm{mflow}=\mathrm{port_a.mflow}$ $\mathrm{hflow}=\mathrm{actualStream}\left(\mathrm{port_a.hflow}\right)$ $\mathrm{ρ}=\mathrm{actualStream}\left(\mathrm{port_a.rho}\right)$ $T=\mathrm{actualStream}\left(\mathrm{port_a.T}\right)$ $v=\frac{\mathrm{mflow}}{\mathrm{actualStream}\left(\mathrm{port_a.rho}\right)\cdot A}$ Port's variable definitions: $\mathrm{port_a.p}=\mathrm{port_b.p}$ $\mathrm{port_a.mflow}+\mathrm{port_b.mflow}=0$ $\mathrm{port_a.hflow}=\mathrm{inStream}\left(\mathrm{port_b.hflow}\right)$ $\mathrm{port_b.hflow}=\mathrm{inStream}\left(\mathrm{port_a.hflow}\right)$ $\mathrm{port_a.rho}=\mathrm{inStream}\left(\mathrm{port_b.rho}\right)$ $\mathrm{port_b.rho}=\mathrm{inStream}\left(\mathrm{port_a.rho}\right)$ $\mathrm{port_a.T}=\mathrm{inStream}\left(\mathrm{port_b.T}\right)$ $\mathrm{port_b.T}=\mathrm{inStream}\left(\mathrm{port_a.T}\right)$
