Problem 1. (10 pts) Starting with the general conservation of linear momentum equation, derive the relationship between pressure and position along the z axis, i.e., p=f(z), and value of p at z=L for water inside a vertical cylinder with a circular cross-section, as diagramed below. Show and justify all of the steps in your derivation. Assumptions: - Newtonian fluid - Incompressible fluid - Cylinder is full of water and open at the top to the atmosphere, with atmospheric pressure =0 (gage pressure) - Cylinder is closed at the bottom - There is no flow: v=0
