drag force


Also found in: Acronyms, Encyclopedia, Wikipedia.

drag force

a retarding force, acting opposite to the direction of motion of a body or object. Often caused by air resistance or friction. form drag the resistance force caused by the shape of a body or object which is moving through a fluid medium. surface drag the force, opposing the direction of motion, that is due to the interaction between the surface of an object and the medium through which it is passing (or that is moving past it). propulsive drag force the force used by sportspeople to propel themselves, usually by pushing against a fluid medium (e.g. swimmers or rowers).

that can increase drag forces (by increasing the effective d without increasing [[rho].
Since it is difficult to accurately measure static pressure in wake zone of the body, Goldston [15] considered static pressure in that area according to equation 8 as three-dimensional turbulence intensity and calculated drag force coefficient like equation 10:
The drag force on the plate is found to increase due to the transverse magnetic field and dissipative heat.
Representative drag force and rotation pulse data from this first set of lubrication tests at [DELTA]p = 0 MPa with N = 1800 rpm and [F.
The drag force (since it is acting up-ward in this case) will serve to increase the area of the piston by an amount of about 44.
This beam is mounted on a milling machine to achieve a controlled cutting speed, with variable blade orientation with respect to the test material being cut, to provide basic cutting and drag force data for linear cutting.
Despite this theory, the transport of sand from a turbulent runner system into the mold cavity is unlikely because the minute grain area presents such a small cross section that any drag force on the sand is minimal.
The drag force is the force that has to be overcome to move the pipes mounted in the welding fixtures.
In the case of fluid bed roasters, the air drag force lifts the coffee in the air stream causing it to levitate, or float, in the air stream.
Local morphing of selected regions proportional to the sensitivities, is then applied to generate an improved shape that leads to a reduced drag force.
A movement of body in the fluid is affected by a drag force which resists and slows the motion.
