WebThe flow rate value can be determined using a formula; the larger the value, the higher the flow rate will be through the valve at a given pressure drop. Flow rate is expressed as Cv or Kv, depending on the system of measurement being used (imperial or metric, respectively). The minimum required Cv value is often listed in a valve’s product ... WebSep 12, 2024 · where V is the volume and t is the elapsed time. In Figure 14.7.3, the volume of the cylinder is Ax, so the flow rate is. Q = dV dt = d dt(Ax) = Adx dt = Av. The SI unit for flow rate is m 3 /s, but several other units for Q are in common use, such as liters per minute (L/min). Note that a liter (L) is 1/1000 of a cubic meter or 1000 cubic ...
WebVolumetric Flux is actually this flow rate per unit area, i.e. V/t.A, symbol q (units m^3/s.m^2). ... We could just go back to our basic kinematic formula: distance is equal to rate times time. The distance something travels equals velocity times time, so after T seconds, whatever fluid was here, it would have an area of about that much. ...
