The Froude number is a dimensionless group that compares inertial forces to gravitational forces in a stirred tank. It is used in process engineering to predict surface phenomena such as vortexing or gas entrainment, particularly in unbaffled or partially-baffled systems. This calculation is critical for scaling-up agitated processes in various industrial applications.
