Help with calculus/physics q

  1. Jan 26, 2006 #1
    this is a question about a steam engine with the equation (sorry for lack of proper math language)

    PV^1.4 = k (constant)


    using the idea of integral from V1 to V2

    ie...


    the amount of work done is W=(int.V1 to V2) PdV

    Where P1=160lbs/in^2
    and V1 = 100 in^3.....V2=800 in^3

    solving for P we can find P=kV^(-1.4)...where k is 100953.1751

    now i solved for in the integral

    160*(100953.1751) *[ .4 V^.4] from 100 to 800 (for V)

    i found W=9.35 * 10^11


    Did i do this properly?
    thanks for the help.
