Given a cross sectional area of A=10cm^2
1kg each of water ( ρ = 1000 kg/m^3 ), olive oil (
ρ = 800 kg/m^3 ), and mercury ( ρ = 13600 kg/m^3 ) are poured, and allowed to settle. What is the
pressure at the bottom of the pipe?
The Attempt at a Solution
I have set up a free body diagram of the system with ∑Fy= PA-mg-PoA= o, but I'm not sure what to do at this point.
