If the velocity term in the Bernoulli equation is zero, it means that the velocity of the fluid at that particular point is zero. In this case, the equation simplifies to:
Pressure + 0.5 * Density * Velocity^2 = Constant
This equation states that the pressure at that point plus half the product of the density and zero (which is zero) is equal to the constant. Therefore, if the velocity term is zero, the equation reduces to:
Pressure = Constant
This means that the pressure at that point remains constant throughout. It suggests that even with zero velocity, there can still be a non-zero pressure. This situation often occurs in fluid dynamics when considering static or stagnant fluids, where there is no flow or movement.
