# Dimensionless Number

- Cavitation Number - The Cavitation Number is a dimensionless number used to characterize the potential of cavitation in a liquid, important in hydraulic equipment design.
- Péclet Number Calculation - Calculate the Péclet number, a dimensionless number indicating the relative importance of advection to diffusion in fluid flows. It uses fluid velocity, characteristic length, and diffusivity.
- Schmidt Number Calculation - The Schmidt number is a dimensionless quantity expressing the ratio of fluid's viscosity to its diffusivity. Calculate it here for various substances.
