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 friction, which … 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 As mentioned, the drag equation with a constant drag coefficient gives the force experienced by an object moving through a fluid at relatively large velocity (i.e. high Reynolds number, … 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. From the body's perspective (near-field approach), the drag results from forces due to pressure … 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 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 drag equation: $${\displaystyle F_{D}\,=\,{\tfrac {1}{2}}\,\rho \,v^{2}\,C_{D}\,A}$$ where 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 … See more

Fluid resistance Article about fluid resistance by The Free Dictionary

WebIn 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 a fluid and a solid surface.. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag … WebThe form of the resistance is. where ρ is the air density, A the crosssectional area, and C is a numerical drag coefficient. The drag coefficient C is 0.5 for a spherical object and can reach 2 for irregularly shaped objects according to Serway. An object falling through the air will reach a terminal velocity when the drag force is equal to ... how many monasteries are on mount athos
