SUMMARY
The pressure at the center of a potential vortex, described by the velocity equation Vθ = a/r, is determined to be negative infinity (p = -∞). This phenomenon occurs because the centripetal force required to maintain the swirling motion of the fluid is derived from the difference between the vortex pressure and the surrounding atmospheric pressure. As the radius approaches zero, the pressure within the vortex decreases without bound, leading to an infinite negative pressure state.
