Consequentially, the

drag force induces shear stress [[tau].

T] = Re ([upsilon]/d), where Re is the Reynolds number, we see that the upper limit for the volume of a particulate for which the settling velocity and the

drag force are linearly related is given by the formula

The

drag force does not dominate the behaviour, but rather only mildly alters the motion.

The power loss of the

drag force transfers from the fluid to the particle and hereby requires that Equation 10 equals 1.

Flow turbulence in rough model compared to smooth one could cause momentum to penetrate into the low-pressure zone and make a delay in separation point and consequently reduce

drag force applied on model which is our main purpose of roughening the vehicle.

The arm model rotated due to the gravity of the weight through the chain, and the

drag forces acting on the hand were measured with the load cell.

Aerodynamic

drag force is the force opposing the motion of the platform due to air drag, wind resistance.

These flows are very complex and influenced by various physical phenomena, such as particle-turbulence and particle-particle interactions, deposition, by gravitational and viscous

drag forces, particle rotation, and lift force.

A solid body (mine imitator) moving in the fluid is influenced by

drag force, thus, in order to overcome it, another force is necessary.

But di Resta concedes he faces a massive fight on his hands to help

drag Force India towards respectability this season.

Thus, the pressure on the airfoil surface increases, the suction decreases, the elevating force decreases,

drag force increases, and under the same angle of incidence, the more is the Reynolds numbers, the more is the lift coefficient.

drag force on the plate is increased due to the magnetic field effect or the effect of dissipative heat Further we can conclude from these two figures that the skin-friction [tau] is not significantly affected by the frequency of oscillation [omega]
