Definition | An <EULER NUMBER> is a <PhysicalObject> that has An <Property> related to fluid flow calculations. It is a dimensionless number that expresses the relationship between a local pressure drop caused by a restriction and the kinetic energy per volume of the flow, and is used to characterize energy losses in the flow, where a perfect frictionless flow corresponds to an Euler number of 0. It is calculated as Eu = deltap/(rho.v^2) where delta p is pressure, rho is <MASS DENSITY> and v is <SPEED> |
