| The basis of the general mathematical description of flow is the equilibrium of mass, momentum and energy. A flow is described, if at any place and at any time the velocity vector and the values pressure and temperature in the flow domain are known. For the calculation of these values, the conservative equations and the constitutive equations are combined | The basis of the general mathematical description of flow is the equilibrium of mass, momentum and energy.

| i.e. if the characteristic curves of the conveying channels are known, those of the reconveying channels can be deduced from this basis. | i.e. if the characteristic curves of the conveying channels are known, those of the reconveying channels can be deduced from this basis. | ||
| - | The characteristic curve to specify the transportation | + | The characteristic curve to specify the neutral elements correspond with the specification in zone III, as the drag conveying capacity equals zero and as, therefore, the element is always overrun. The figure displays the pressure-throughput characteristics for the three types of transport and varying exponents of the power law. It can be recognized that the above outlined transformation of the characteristics allow a sufficiently good description of the Poly-flow results. |
