अवधारणा:

द्वि-विमीय प्रवाह के लिए कोणीय वेग:

\(ω=\begin {vmatrix} i & j \\ {\partial \over \partial x} & {\partial \over \partial y} \\ u & v \end {vmatrix}\)

ω = \({\partial v\over \partial x}-{\partial u\over \partial y}\)

यदि कोणीय वेग शून्य (ω = 0) है तो प्रवाह अघूर्णी होगा।

0 = \({\partial v\over \partial x}-{\partial u\over \partial y}\)

\({\partial v\over \partial x}-{\partial u\over \partial y}\)

संबंध \(\frac{\mathrm{d} v}{\mathrm{~d} x}=\frac{\mathrm{du}}{\mathrm{dy}}\) अघूर्णी प्रवाह के लिए लागू होता है। अतः विकल्प (1) सही उत्तर है।
