Homework Statement
Does the delay of propagation of pressure gives a torque during a short time ?
A disk full of a liquid turns at a constant angular velocity w around the red axis. At a time, a valve move out, this will increase quickly the pressure inside the liquid.
1/ Draw the lines of equal pressure from the valve
2/ Draw the forces from this additionnal pressure
3/ Is there an additionnal torque ?
