Calculating LEV face velocity to hold plate in place.

  1. Jan 28, 2014 #1
    LEV needs to be at 1m/s at the face.
    Let’s say area of LEV is .1 m2
    What size plate (with holes or not in it) and weight is needed for the plate to fall off if the face velocity is less than 1m/s but the velocity is enough to keep the plate on the lev face if the speed is 1m/s or greater. I think the plate needs holes as otherwise it would be just suction rather than velocity keeping the plate in place.

    I have no idea where to start.

    What's an LEV?
