Variables Used
Reynolds Number - The Reynolds number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities. A region where these forces change behavior is known as a boundary layer, such as the bounding surface in the interior of a pipe.
Static density - (Measured in Kilogram per Meter³) - Static density, is the density of the fluid when its not moving, or the density of fluid if we are moving relative to the fluid.
Static velocity - (Measured in Meter per Second) - Static velocity is the velocity of fluid at a point in the fluid, or velocity in the continuous flow.
Boundary-layer momentum thickness for transition - (Measured in Meter) - Boundary-layer momentum thickness for transition is defined in relation to the momentum flow rate within the boundary layer.
Static viscosity - (Measured in Pascal Second) - Static viscosity, is the viscosity of continuous flow, viscosity measures the ratio of the viscous force to the inertial force on the fluid.
