The velocity components of a two dimensional plane motion of a fluid are: \(u = \frac{{{y^3}}}{3} + 2x - {x^2}y\) and \(v = x{y^2} - 2y - \frac{{{x^3}}}{3}\).
The correct statement is:
1
Fluid is incompressible and flow is irrotational
2
Fluid is incompressible and flow is rotational.
3
Fluid is compressible and flow is irrotational.
4
Fluid is compressible and flow is rotational
