Document Summary
Volume (v) and density (p = m/v) are constant and don"t depend on pressure. Deformable under the influence of forces and seeks mechanical equilibrium. Use equation to find relation between pressure and depth. Fnet,y = 0 = fup w - fdown. M = p * v = p * a * y. W = m * g = p * g * a * y. Volume to show horizontal surface area of water rand p density of the fluid. Two contact forces in equation 1 are replaced by pressure terms (p * a) ((p + p) * a) (p * g * a * y) = 0. P = -p * g * (y2 y1) Used when the surface of the fluid cannot be identified and thus cannot be a reference point. Blood in the cardiovascular system (close system with no identifiable surface)
