The general equation simplifies to: F = (m dot * V)e + (pe - p0) * Ae We … In fluid dynamics, drag (sometimes called fluid resistance) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between an fluid and a solid surface. Unlike other resistive forces, such as dry … See more Examples of drag include the component of the net aerodynamic or hydrodynamic force acting opposite to the direction of movement of a solid object such as cars (automobile drag coefficient), aircraft and boat hulls; or acting … See more Drag depends on the properties of the fluid and on the size, shape, and speed of the object. One way to express this is by means of the See more The equation for viscous resistance or linear drag is appropriate for objects or particles moving through a fluid at relatively slow speeds where there is no turbulence (i.e. low Reynolds number, $${\displaystyle R_{e}<1}$$). Note that purely laminar flow … See more In 1752 d'Alembert proved that potential flow, the 18th century state-of-the-art inviscid flow theory amenable to mathematical solutions, resulted in the prediction of zero drag. This was in contradiction with experimental evidence, and became known … See more Types of drag are generally divided into the following categories: • form drag or pressure drag due to the size and shape of a body • skin friction drag or viscous drag due to the friction between the fluid and a surface which may be the outside of an object … See more As mentioned, the drag equation with a constant drag coefficient gives the force experienced by an object moving through a See more In aerodynamics, aerodynamic drag (also known as air resistance) is the fluid drag force that acts on any moving solid body in the direction of the air freestream flow.
