    Critical Velocity for Air pockets

    Thank you Bris, yes the formaular is from HR Wallingford. My confusion is that if I have a slope of 1/125, so do I take ATAN of this slope and then convert the result to degrees OR take the sin(1/125.

    Critical Velocity for Air pockets

    Thank you RWF7437 and theci. theci in your formular, if you have a slope of 1/125 what will be the ?. Is it the ATAN(1/125) or ATAN(1/125) converted to degrees. Thanks,

    Critical Velocity for Air pockets

    I am trying to use the formular V/sqrt(gD) = a + 0.56sqrt(sin S) to calculate the critical velocity on a downward slope of 0.0057 and I can't quiet get IF S (slope) is in radians or degrees. Using either unit gives diffrerent answers. I would like to know if its radians or degrees.
