Drag coefficient for a spherical object in creeping flow
Description
In fluid dynamics, the drag coefficient is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water. For a spherical object,moving under creeping flow conditions, the drag coefficient depends on the sphere’s weight and the fluid properties.
