WebbSurface drag is also known as skin friction. As air or fluid molecules slide over the surface of an object friction slows them and this impacts on the object because the velocity is slowed. The roughness of a surface increases drag, for example a tennis ball has a rougher surface, compared to a golf ball. WebbThe most familiar fluid is of course water, and an encyclopaedia of the 19th century probably would have dealt with the subject under the separate headings of hydrostatics, the science of water at rest, and hydrodynamics, the science of water in motion.

http://hyperphysics.phy-astr.gsu.edu/hbase/airfri.html WebbFluid Friction. When moving through a gas (air) or liquid (water), there is some from of friction. This is called fluid friction. Observe the animation to the left, in both cases fluid friction is pushing up and slowing the fall. This is because, as the objects fall water molecules push against it, generating friction.

The equation is easier understood for the idealized situation where all of the fluid impinges on the reference area and comes to a complete stop, building up stagnation pressure over the whole area. No real object exactly corresponds to this behavior. is the ratio of drag for any real object to that of the ideal object.

Webb13 apr. 2024 · Air resistance is a good example of drag force, which is the force that objects feel when traveling through a fluid. The drag force, like kinetic friction, is a reactive force that arises only when an object is moving and points in the opposite direction of the object’s motion through the fluid. Shape drag and skin drag are two types of this ... WebbExamples of Laminar Flow. 1. Blood Flow. The blood flowing in our veins undergoes laminar flow. The adjacent layers of the blood get mixed with each other on a molecular level; however, they remain separated on the macroscopic level. This is the reason why the blood within the veins appears to be flowing in a straight line. 2.
