Consider a two-dimensional flow which varies in time and is defined by the velocity field, u = 1 and v= 2yt. d) Do the fluid elements experience angular rotation? Thus, state whether the flow field is rotational or irrotational. e) Given that the density of the fluid does not vary spatially and changes only with time, what differential equation for the density, p(t), must be satisfied for this scenario to represent a physical, compressible flow field? f) At time t = 0, the density everywhere is p = po. Determine how the density changes with time, given the situation does represent a physical, compressible flow field.
