For the following velocity profiles state whether they are steady or unsteady and whether they are 1-D, 2-D or 3-D.
For part c, assume a and b are 1. Is the flow irrotational?
For part d, write and expression for a in terms of b that makes d irrotational and find the stream function.
a) V=[a(x^2)(e^(-bt))]i
b) V=ax^2i+bxj+ck
c) V=[ae^(-bt)]i+bx^2j
d) V=axi-byj
