flow equation [′flō i‚kwā·zhən] (fluid mechanics) Equation for the calculation of fluid (gas, vapor, liquid) flow through conduits or channels; consists of an interrelation of fluid properties (such as density or viscosity), environmental conditions (such as temperature or pressure), ...
If the volumetric flow rate was given, the mass flow can be found by multiplying the density of the fluid with the volumetric flow rate: Q * density. What is the formula for volume flow rate? The volume flow is the change in volume per change in time: dV/dt = (V_2 - V_1)/(t...
When the limits of the full film zone are well defined the pressure is usually prescribed on the boundary of the full film zone. In the case of free boundaries for the formation or the rupture of the film, continuity of the average flow rate must be prescribed on the free boundaries. ...
It is clear that the functions fj, for any j, are asymptotically equivalent (in the limit N→∞) to the functions f˜j, so that it will be the same to work with this new sequence. Moreover, if ∏i=1j∏k=j+1Nχ(|xi-xk|>ε) equals to 1, since the range of the interaction...

Although the viscous resistance of a normal gas attenuates the flow rate significantly, we have assumed that the attenuation is relatively constant, and does not vary significantly with the ratio of the pressure difference to inlet pressure. Under these conditions the ideal gas equations can be ...
The aim of this note is to obtain a flow rate equation for subsonic Fanno flow, which has a form similar to the flow rate equation for isothermal flow. When pipe dimensions and the proper values of pressures and temperatures at two sections along a pipe, namely P-1, P-2, T-1 and T...
