Tennis Ball Drag Coefficient at Eva Dolling blog

Tennis Ball Drag Coefficient. This actually simplifies the analysis of ball motion since. Relatively high drag coefficients (cdffi0.6 to 0.7), have been measured for new nonspinning tennis balls. For the four types of tennis balls tested, used balls showed higher in drag coefficient than new balls, and new balls tended to be higher than used. The drag coefficient is defined as, co =d/(y2 pu2a), where d is the drag force,. The flow of air around a tennis ball is turbulent at all ball speeds of interest in tennis, due to the relatively rough surface of the ball. The observed (unexpected) behavior of. Drag coefficient (cd) is plotted against the reynolds number. The sudden drop in cd at ball speeds above 10 or 20 m/s is called the \drag crisis and represents a change from smooth or laminar ow of air around the ball surface at low speeds, to. In the second phase of the experiments, the drag coefficient of a variety of new and used tennis balls, including prototypes. Aerodynamic force (drag and lift) measurements for nonspinning and spinning balls are reviewed for a wide range of reynolds numbers and spin rates.
