9000rpm*(1min/60sec)*(1rotorrev/3shaftrevs)*(2*pi*rotorradius)



course now i'm gettin 111 feet/sec. i suck with windows calc



and this doesn't take into account the fact that the apex seal is not always perpendicular to the housing, and that the absolute angular velocity of the seal isn't constant, etc.
