Velocity potential (φ) is a scalar quantity that describes the fluid flow in terms of a scalar field. It represents the rate of change of fluid velocity with respect to spatial coordinates. In potential flow theory, the velocity components of the flow can be derived from the gradient of the velocity potential, which is why the unit for velocity potential is expressed in square meters per second.
