1. The problem statement, all variables and given/known data Please see attached file for problem statement 2. Relevant equations ΣM = Min - Mout = 0 3. The attempt at a solution I have tried using the equation of conservation of momentum on this problem but I'm getting stuck at how the viscous force of the liquid is playing a role in this problem. In addition, would I take in affect that the force of the liquid that is applied on the cone is applied throughout the whole area of the cone, therefore, meaning that I need to find the area of the surface of the cone that the liquid is acting upon?
