engineering problem.   The Reynolds Transport theorem for conservation of mass is as follows (dmdt)syst=(∫cv∂ρ∂tdV)+∑(ρAV)out−∑(ρAV)in=0     If the flow in the

plzzzz help meeeeee right nowwwww

For a flow in the xy plane, the x component of the velocity is u=3x2y-y3is given. Determine the y component for steady state and incompressible flow. Does this result also apply to unstable, incompressible flow? Why is that? How many possible y components are there? Discuss.
