Minor loss coefficient

  1. Jun 25, 2015 #1
    Hi everyone;

    How I can define the minor loss coefficient(pressure loss) of a filter which has 60nm pore diameter?

    Beats me. Generally, such information is obtained from testing the filter to obtain a curve of pressure drop versus flow rate. This is the procedure even for things like strainers, where the perforations are much larger than 60 nm

    What SteamKing said. The only way is to measure it, or check if somebody else has already measured it.
