a test tube standing vertically in a test-tube rack contains 2.5 cm of oil. Density of oil is .81 g/cm^3 and it contains 6.5 cm of water. What is the pressure on the bottom of the test tube?
What is the absolute pressure?

Pressure P at the bottom of a column of liquid is equal to


P = \Sigma {\rho} h


where \rho is the density of each liquid and h is the height of each liquid in the column.
