For a two dimensional, incompressible flow having velocity components u and v in the x and y directions, respectively, the expression \(\frac{\delta(u^2)}{\delta x} + \frac{\delta(uv)}{\delta y}\) can be simplified to
1
\(u \frac{\delta u}{\delta x} + u \frac{ \delta v}{\delta y}\)
2
\(u \frac{\delta u}{\delta x} + v \frac{ \delta u}{\delta y}\)
3
\(2u \frac{\delta u}{\delta x} + u \frac{ \delta v}{\delta y}\)
4
\(2u \frac{\delta u}{\delta x} + v \frac{ \delta u}{\delta y}\)
