Webb8 apr. 2024 · Pascal’s Law quantitatively within a fluid can be derived from the expression that determines the pressure at a given height (or depth) and is defined by Pascal’s Principle: p2=p1+ Δp. Δp=ρgΔh. Where, p1 = externally applied pressure. ρ = density of the fluid. Δh = difference in height of the static liquid. WebbThis is shown in Fig. 15.1 (b), by Mohr’s circle (II), in which σ h = σ 3 = OA 2 is the reduced lateral earth pressure while the vertical stress, equal to σ v = σ 1 = OB, remains constant. The decrease in the lateral earth pressure thus causes increase in the diameter of Mohr’s circle, causing it to approach the Coulomb’s failure envelope.
