For a two dimensional, unsteady flow of an incompressible fluid, the velocity field is given by V(2x2 t + y) î - 4xyt ĵ Then which of the following statements are true?
1
Fluid flow is not possible.
2
Convective acceleration in x-direction at (1, 2) and t = 3 sec is + 72 m/s2
3
Local acceleration in y-direction at (1, 2) and t = 3 sec is 8 m/s2
4
Total acceleration at (1, 2) and t = 3 sec is 114.97 m/s2
