WebMay 13, 2024 · The drag coefficient is a number which engineers use to model all of the complex dependencies of drag on shape and flow conditions. The drag coefficient Cd is equal to the drag D divided by the … Webpressure drag. 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.
