Vena Contracta K Factor

  1. Nov 21, 2012 #1
    To calculate the K factor for a contraction, do you find the inlet pressure and outlet pressure and then find the difference, then divide the pressure difference by rho x gravity to find the value of h and then rearrange h = K (V2/2g) to find K because im unsure otherwise?

    What else one can do?

    Cheers. Am i right in thinking the pressure difference between the actual pressure drop and ideal pressure drop should be used to find h for use in the eqtn?
