# Pressure at the bottom of a glass pipe?

## Homework Statement

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?

F=PA
P=Po+ρgd

## 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.
