Drag vs velocity graph
WebFeb 2, 2011 · At high gas velocitiy, the drag coefficient also depends on the Mach number Ma = u/a, where a is the velocity of acoustic waves in the gas. At Ma < 1, a formula approximating a vast body of experimental … Web[2][3]Drag force is proportional to the velocity for low-speed flow and the squared velocity for high speed flow, where the distinction between low and high speed is measured by the Reynolds number. Drag forces always tend to decrease fluid velocity relative to the solid object in the fluid's path. Examples[edit]
