What does D stand for?

When a star encounters a relatively dense clump of this gas, the resulting flow produces a drag force on any orbiting dust particles.

Once the polymer melt exits the die, very high velocity heated air impinges on it and the resultant drag force attenuates the molten polymer within microseconds to fine fibers having diameters in the range of 1-20 microns.

So, as speed increases, subjects are submitted to an increasing drag force as well, and need a higher metabolic power to overcome such external force.

4) All variables used in the equations above are defined in the following table: Drag Force [F.

The drag force exerted on the fixed plate is the frictional force, represented by [F.

Driving slower will definitely increase your mileage since the drag force used is also lower.

In order to generate drag force, the frontal area of the limbs used for stroking, primarily the hands should be maximized in order to achieve the desired thrust.

The more recently investigated mechanism concerns the decrease in effective posterior restraint (increased leaflet slack) caused by anterior redirection of papillary muscle tension; increased length of the residual leaflet, which is relatively free to move anteriorly, unlike the coapted leaflet bodies; and interposition of the leaflets into the path of outflow with the potential to cause drag forces (pushing forces of flow) (5, 6).
