Homework Statement
A U-shaped tube with a horizontal segment of length L contains a liquid. What is the difference in height between the liquid columns in the vertical arms if the tube is mounted on a horizontal turntable, and is rotating with angular speed w, with one of the vertical arms on the axis of rotation?
Homework Equations
a=w^2r towards the centre
p = p(o) + density*g*h
The Attempt at a Solution
A previous part to the question was finding the difference in height if the U-tube had acceleration a towards the right. I did this and found h=aL/g.
I was thinking I could just substitute a=w^2L into this equation but then I had second thoughts since the acceleration decreases as you get closer to the axis of rotation. Do you take the average acceleration intead?
Thanks.
