In so doing, the spherical body placed on analytical scales was spinned and blown by the flow with a given velocity. The out-of-balance caused by the Magnus force was measured, and the CM coefficient in the Rubinow - Keller formula was determined. The dependence of CM upon two Reynolds numbers, Reω and Rep, in the ranges of 590 < Reω < 45000, 360 < Rep < 13500 was determined. At fixed Rep the value of CM decreases with the increase of Reω; while at Reω = const it increases. For low Reω the CM coefficient approaches to estimates by Rubinow and Keller. With using the obtained results literature data a generalizing formula for CM is offered. %8 2005-05-07
