Need help with an equation.

  1. May 3, 2013 #1
    Hello, could someone please solve this for me?
    Or try and help me at least...
    FD = 1/4 AV^2 / FD=(1/2)pv2AC

    What do you want it solved for? I don't even understand the equation(s), please use more brackets to make the division clearer.

    This needs some context.
    Are FD and AC single items or the product of F & D, A & C respectively? Similarly for AV & pv.
    What unknown are you trying to solve for?

    If the second part is written as
    FD = 0.5ρACv2 it is an expression to calculate friction drag (FD?) through air.
    A is the cross section area, C is a drag coefficient, ρ = density of fluid (air for example)

    Yes , it is indeed to calculate the friction drag through the air, but i want to know the answer, kind of.
    Have been trying to solve this for a long period of time and cant stop thinking about it.
