Homework Help: Need help with this(dimensional analysis)

  1. Jun 25, 2006 #1
    It is observed that the velocity 'v' of a liquid having a nozzle depends upon the pressure drop 'P'and the density'p'.Show that the relationship between them is of the form.

    v=C[P/p]raised to power of 1/2

    What are your thoughts? What do you know?

    Write v, P and [itex] \rho [/itex] in terms of the three fundamental units: kg, meter and second. Then the answer should be obvious.
