Problem 3.16 [Difficulty: 2] p atm A p base A Cover Given: Data on water tank and inspection cover Find: If the support bracket is strong enough; at what water depth would it fail Assumptions: Water is incompressible and static Solution: Basic equation dp dy ρ g = or, for constant ρ Δ p ρ g h = where h is measured downwards The absolute pressure at the base is p base p atm ρ g h + = where h1 6 f t = The gage pressure at the base is p base ρ g h = This is the pressure to use as we have p atm on the outside of the cover. The force on the inspection cover is Fp base A =
