    Why is my answer of 2.3 cm wrong for the pressure ratio formula?

    Yes, I think I get it now. The formula really doesn't look correct. I believe the one you mentioned above is the right one to use. Thank you :)

    Why is my answer of 2.3 cm wrong for the pressure ratio formula?

    Is it done by using the formula p2/p1= r1/r2? I got answer 2.3 cm but it comes out it is wrong. Why?
