1. The problem statement, all variables and given/known data Basically, the goal of the "project" is to find the equation for oscillation of a "fractionless" fluid in a v-shaped tube, regarding the angle. I know how to solve the same problem regarding a u-shaped tube, but in this case, I can't figure out where to place the angle in the equation... Does the angle even affect the osciallations at all? From where I am now, it seems like it doesn't, but I doubt that's true. Any help is appreciated, thank you :) 2. Relevant equations Simple harmonic motion equation. 3. The attempt at a solution So, I'm currently at w(angular frequency)=sqrt[2*g/(hl+hd/cos(angle)].... is that right?
