Velocity potential is a scalar quantity that describes the rate of change of potential energy per unit mass of a fluid flowing past a fixed point in the fluid. It is defined as the negative time rate of change of the potential energy of a fluid element.
It is a conserved quantity, meaning that its value remains constant for a closed system of flowing fluid. This means that if you take the time derivative of the velocity potential with respect to time, you will get the velocity of the fluid at that point.
The velocity potential is a fundamental quantity in fluid dynamics, as it is used to determine the flow velocity of a fluid around an object. It is also used in the study of the interactions between fluid flow and solid boundaries.
The velocity potential is defined as the negative time rate of change of the potential energy of a fluid element, and is a scalar quantity that is defined for every point in the flow. It is measured in the same units as velocity, which is also a scalar.
For a fluid element moving in the x-direction, the velocity potential is given by:
where (\psi) is the potential function.
