Critical Flow Calculator

Flow can be defined as the amount of fluid that passes through a surface at a certain point of time. The ratio of the inertial force to the gravitational force representing the different flow on a free surface is the froude number. If the froude number is less then 1, it is subcritical, greater than 1 it is supercritical and when equal to 1, it is critical. This calculator is used to find the state of flow based on the froude number with gravity, velocity and depth.

William Froude derived the froude number who gave the speed-length ratio and hence froude number is based on ratio.
