These effects are also shown to be strongly size dependent with finer particles being much more susceptible to drag forces from the air flow.
The fuel flow model is a simplified momentum equation which is based on the momentum balance considering the fuel inertia, gravity, and drag force from gaseous and solid phase.
The stress was revealed by the deflection of a nanofiber, caused by the drag force from a broad stream of air, which flowed perpendicular to the fiber at a known velocity.
There's a very slight -- but non-negligible -- drag force from the very tenuous atmosphere at those high altitudes.
Then consequently, the smaller viscous drag force from water at 100 °C correspondingly requires smaller DEP force, which coincidentally meets the requirement.
Typically, increasing the number of blades installed to the VAWT can achieve high drag force from any direction of the wind [26].
For a conservative estimate of this drag force from the innermost ejecta, we neglect any outward velocity of this gas, and take a density of 10−3 g cm−3 in this material.
The possibility of the coal particle moving toward the CDRS inner wall is mainly affected by the drag force from the air current and the centrifugal force of the particle by itself, and etc. Ignoring other effects, it is desirable that the moving coal particle should be affected by the centrifugal and drag forces.
For some types of self-interactions, the passage of a galaxy through some background dark matter overdensity will cause a separation between the centroids of the collisionless stars and the dark matter halo of the galaxy, which experiences a drag force from the self-interactions.
Any object being pulled by a rope that experiences a "drag" force from friction against another object (or fluid) transfers this force to the tension in the rope.
