Fluids Mechanics, Momentum

    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?

    You need to use calculus to do the change in momentum.

    Are you learning about macroscopic momentum balances in your course? In your relevant equation, does M stand for mass or for momentum?
