Homework Statement
A tube of uniform cross-section is bent to form a circular arc of radius R, forming three quarters of a circle. A liquid of density ρ is forced through the tube with a linear speed 'v'. Find the net force exerted by the liquid on the tube.
Homework Equations
F = ρav2 ?
The Attempt at a Solution
Since the arc is three quarters of a circle, the water travels through 3∏/2 radians (Is this relevant?). Since it says net force, then the force exerted by the liquid must be greater than that exerted by the tube on the liquid. I am not sure what to do next.
