Homework Help: Pressure Question

  1. Mar 27, 2010 #1
    1. The problem statement, all variables and given/known data
    A test tube standing vertically in a test-tube rack contains 2.5cm of oil (Density=0.81 g/cm^3) and 6.5cm of water. What is the pressure on the bottom of the test tube?

    2. Relevant equations

    P=Dhg where d=density, h=heigh, and g=gravity.

    3. The attempt at a solution

    P=(0.81)(9cm {2.5cm+6.5cm})(9.80)

    P=71.442 Pa

    Is this correct?
