Hartmann number (Ha) is the ratio of electromagnetic force to the viscous force first introduced by Hartmann.
In science and engineering, the weight of an object is usually taken to be the force on the object due to gravity.
In Newtonian physics the weight is
he Bagnold number (Ba) is the ratio of grain collision stresses to viscous fluid stresses in a granular flow with interstitial Newtonian fluid, first
Bernoulli’s principle states that for an inviscid flow, an increase in the speed of the fluid occurs simultaneously with an increase in dynamic
In fluid mechanics, the Roshko number is a dimensionless number describing oscillating flow mechanisms.It is related to the Strouhal number and the
