Help with conversion of equation

  1. Jun 10, 2005 #1
    Hey guys, I'm trying to convert this equation into terms of y

    Q = C (of v) ^n
    Q = C (of rho.v) ^ y

    v is the veloctiy and rho v is the flow of a material although that doesn't really matter. C is a contant, and rho is equal to 1.42.

    When i write of v - i mean if writing it out on paper i would write C with a little v beneath it - the same with rho v.

    Dots mean multiplication.

    Please help me soon i'm sure i'm being dense but need help!! Also my value for rho might be wrong!

    [tex]Q = C_v ^n[/tex]
    [tex]Q = C_v ^ y[/tex]

    Solved for y?
    Just use logarithms.

    Whozum -
    in the first equation, it is C of v as you wrote
    but in the second equation, it is C of rho times v

    So logarithms cannot be used can't they?

    That doesn't make sense. The subscript is used to identify or elaborate on the variable, it doesn't hold any mathematical informaiton.

    i agree with whozum. you should just use logarithms. it doesnt matter about the subscript.
