Mathematically, what is meant by Kelvin’s Circulation Theorem for an inviscid and incompressible flow? (For the same set of fluid elements moving in a closed curve along with the fluid).

Mathematically, what is meant by Kelvin’s Circulation Theorem for an inviscid and incompressible flow? (For the same set of fluid elements moving in a closed curve along with the fluid). Correct Answer DΓ/Dt = 0

Kelvin’s theorem states that the time rate of change of circulation for a set of fluid elements in a closed curve moving along the fluid is zero. In other words, circulation remains constant, not zero. Γ = -∮C1V.ds is the definition of circulation.
