Homework Help: Interesting Bernoulli

  1. Nov 3, 2009 #1
    1. The problem statement, all variables and given/known data
    I recently was given an interesting problem I thought I'd share with the community here. It's a fun exercise in mathematics. Given the equation:

    Po/P = [1+((k-1)/2)*Ma^2]^(k/(k-1))

    From this stagnation ratio, derive the Bernoulli Equation:

    Po = P + 1/2 * rho * V^2

    Anyway, it's not for homework, so no real need to solve it. Hope you enjoy deriving equations as much as I do. Have fun!

    what are k, M, a?

    k in this case is 1.4 (for air)

    Ma is the mach number.
