Homework Statement
The velocity in a steady helical flow of a fluid is given by:
v1= -Ux2, v2=Ux1, v3=V
where U and V are constant.
show that divv is 0 and find the acceleration of the particle at x.
Also determine the streamlines.
Homework Equations
The Attempt at a Solution
to find the divergence, if we differentiate v1 wrt x1, we get 0, and differentiating v2 wrt x2, we get 0 and differentiating v3 wrt x3, we get 0 so the devergence is 0.
but i am having problem finding the acceleration. i know the acceleration is differentiating the velocity with respect to time but what do they mean 'find the acceleration of the particle at x.' ??
Thank you.
