A flow is described by velocity field, V=ayi+btj, where a=1 s-1and b=0.5 m/s2.At t=n s (Where n is 19), what are the coordinates of the particle that passed through point (1,2) at t=n-1? At t=n+1 s, what are the coordinates of the particle that passed through point (1,2) at t=n+1 s? Plot the pathline and streakline through point (1,2) and compare with the streamlines through the same point at the instants t=n-1 , n and n+1 s.
Consider the following steady, two-dimensional, incompressible velocity field: V = (u, v) = (ax + by²) i + (bx² – ay) j. where a, b, and c are constants. Calculate the pressure as a function of x and y. Check for incompressibility and compatibility as you go. You may stop if at any time you find the velocity field is inappropriate for solution.
If you are 100 % confident then you can solve it otherwise leave it. Thank you
