## Euler Number

The Euler number expresses the relationship between a local pressure drop caused by a restriction and the kinetic energy per volume of the flow.

The Euler number expresses the relationship between a local pressure drop caused by a restriction and the kinetic energy per volume of the flow.

The Eckert number expresses the relationship between a flow’s kinetic energy and the boundary layer enthalpy difference.

Different electrodes have different standard electrode potentials. The standard electrode potentials for some electrodes are negative, while for some others it is positive. The potential values of many electrodes have been measured experimentally and their standard reduction potentials are arranged in sequential order. This arrangement of elements in order of Read more…
