Reynolds Number Calculator
In fluid dynamics, the Reynolds number (Re) is a dimensionless quantity that helps predict fluid flow patterns in different situations by measuring the ratio between inertial and viscous forces.
Prandtl Number Calculator
A dimensionless number, named after the German physicist Ludwig Prandtl, defined as the ratio of momentum diffusivity to thermal diffusivity.
Mach Number Calculator
The Mach Number is the ratio of the object’s velocity to the speed of sound in the same medium.
Strouhal Number Calculator
Calculate the Strouhal Number, a dimensionless number used in fluid dynamics to describe oscillating flow mechanisms.
Grashof Number Calculator
A dimensionless number which approximates the ratio of the buoyancy to viscous forces acting on a fluid.
Froude Number Calculator
A dimensionless number defined as the ratio of the flow inertia to the external force field.
Weber Number Calculator
Calculate the Weber Number, which is a dimensionless number used in fluid mechanics to describe the relative importance of inertial forces compared to surface tension forces.
y+ Calculator
y+ is a non-dimensional number used in fluid dynamics to characterize the boundary layer in wall-bounded flows, particularly in computational fluid dynamics (CFD).
