Problem 3.60 [Difficulty: 2] Given: Plug is used to seal a conduit. γ 62.4 lbf ft 3 ⋅ = Find: Magnitude, direction and location of the force of water on the plug. Solution: We will apply the hydrostatics equations to this system. Governing Equations: dp dh γ = (Hydrostatic Pressure - y is positive downwards) F R p c A ⋅ = (Hydrostatic Force) y' y c I xx Ay c ⋅ + = (Location of line of action) Assumptions: (1) Static fluid (2) Incompressible fluid (3) Atmospheric pressure acts on the outside of the plug. Integrating the hydrostatic pressure equation:
