WebApr 16, 2015 · Drag force on a flat plate. The solution for this apparently is 1 2 C ρ A V 2 where C is the drag coefficient, A is the area and ρ and V are the wind density and velocity. Let's do it without the drag coefficient. Assume that the wind hits the panel normally with speed V and is then stopped (or escapes along the panel). The force on an object that resists its motion through a fluid is called drag. When the fluid is a gas like air, it is called aerodynamic drag or air resistance. When the fluid is a liquid like water it is called hydrodynamic drag, but never "water resistance". Fluids are characterized by their ability to flow.

The last two characters define an applicable power of 10. In fluid dynamics, the drag coefficient (commonly denoted as: , or ) 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. It is used in the drag equation in which a lower drag coefficient indicates the object will have less aerodynamic or hydrodynamic drag.

WebNov 25, 2016 · The drag coefficient cannot be defined unless the reference area is also defined. If you know the drag coefficient (or look it up in a table) you will know how to measure the reference area. You cannot calculate reference area from drag coefficient unless you also know drag force, speed and velocity. WebDrag curve. The drag curve or drag polar is the relationship between the drag on an aircraft and other variables, such as lift, the coefficient of lift, angle-of-attack or speed. It may be described by an equation or displayed as a graph (sometimes called a "polar plot"). [1] Drag may be expressed as actual drag or the coefficient of drag. good names for riverclan cats
