A baseball has a circumference of 9¼ in. and a weight of 5¼ ounces. At 95 mph determine

a. the Reynolds number

b. the drag force

c. the type of flow (see the illustration for Problem 12.7)

Problem 12.7

The drag coefficient for a smooth sphere is shown below. Determine the speed at the critical Reynolds number for a 42-mm-diameter sphere in air.
