Viscous drag calculator

Viscous drag refers to the resistance experienced by an object moving through a fluid due to the frictional forces between the object’s surface and the fluid.

Where:

• $F$ is the viscous drag force
• $Cd$ is the drag coefficient, a dimensionless quantity that depends on the shape of the object and the Reynolds number
• $\rho$ is the density of the fluid
• $A$ is the reference area of the object
• $v$ is the velocity of the object
