Kinetic energy formula

  1. Nov 11, 2013 #1
    Hi Everyone,
    This is a real simple question, but I should make sure I have this right. In the following formula, is the value of P in watts?

    P = 1/2 Aρv3

    I'm assuming that this is in watts, but you know what they say about assuming. Thanks in advance for your help!
    Cheers,
    Rick

    Assuming ρ is in [kg/m3] and v is in [m/s] and A is in [m2], then yes P is in watts.

    Hello MrMatt,
    Thank you very much, I was using Slugs for ρ and A was equal to FT2, but I can convert them to metrics. Glad I double checked!
    Cheers,
    Rick
