engineering recuitment ONGC AEE Mechanical Mock Test 2025 Fluid Mechanics Fluid Kinematics Vorticity and Circulation
Vorticity (ξ) is calculated by:
1
\(\frac{1}{2}\left( \nabla \times \vec{V} \right)\)
2
\(2\left( \nabla \times \vec{V} \right)\)
3
\(\left( \nabla \times \vec{V} \right)\)
4
\(4\left( \nabla \times \vec{V} \right)\)
5
\(\frac{1}{4}\left( \nabla \times \vec{V} \right)\)
