Viscous drag is the force that an object feels as it move through a fluid. It is caused by the viscosity of the fluid which is an innate property of the fluid to resist movement. What is viscous drag formula? The viscous drag formula is given by Newton's law of viscosity, t= nA(dv...
This disparity in velocity is caused by the presence of a force opposing the fluid's motion (or flow). This resistant force is referred to as viscous force.Additional information:Viscous force formula:The viscous force can be estimated by multiplying the surface shear stress by the fluid and ...
For cylinders, convenient formulae are given by[18]. For more general cases, it can be necessary to resort to solving the fluid flow and calculating the drag tensors. At low Reynolds numbers, the fluid flow is described by the Stokes equation: ...

According to formula (1), the viscosity is numerically equal to the tangential force—Ps= F/S(per unit area)—required to maintain a velocity difference equal to 1 between two parallel layers of a liquid or gas whose distance from each other is equal to 1. From this definition it follows...
We name this version the testable unified force formula. After that, a general principle to increase the lift-drag ratio is proposed. Published by AIP Publishing.Liu, L. Q.Peking Univ Coll Engn Ctr Appl Phys &Wu, J. Z.Technol State Key Lab Turbulence &Su, W. D....
The third expression above then expresses that this Peclet number Pe is also the ratio between the maximum magnetic force and the characteristic drag force during the Brownian motion. Actually, it is easy to show that this is the only force competition which is able to explain the breakdown of...
They calculated the drag force on charged cylinders moving at the charged wall. Applying the Derjaguin transformation it is possible to transform their result and apply it to the motion of spherical particle. The resulting approximate formula for the drag coefficient is as follows: (128)λ‖ev=...
