The Euler number ( Symbol : ; by Leonhard Euler ) is a dimensionless number of the similarity theory of fluid dynamics and represents the ratio of compression forces to inertial forces, the same ratio, with an additional factor of two is considered. Pressure coefficient or coefficient, and The connection with cavitation is referred to as the cavitation number . The Euler number is defined as:
Here is the pressure difference , the density and the flow velocity.
