|  | 41. | The friction drag force, which is a tangential force on the aircraft surface, depends substantially on boundary layer configuration and viscosity. 
 
 | 
|  | 42. | For a particle at rest no drag force will be exhibited, which causes the particle to accelerate due to the applied force. 
 
 | 
|  | 43. | A higher volumetric flow rate through a given area increases flow speed and drag force, so the float will be pushed upwards. 
 
 | 
|  | 44. | The vane moves because of the drag force of the air flow against it; it does not measure volume or mass directly. 
 
 | 
|  | 45. | D'Alembert proved that  for incompressible and drag force is zero on a body moving with constant velocity relative to the fluid. 
 
 | 
|  | 46. | For these particles, vertical drag forces due to turbulent fluctuations in the fluid are similar in magnitude to the weight of the particle. 
 
 | 
|  | 47. | This condition resulted in the drag force exceeding the thrust of the hypothetical ramjet in the Zubrin / Andrews version of the design. 
 
 | 
|  | 48. | The rate of sequencing or imaging is dependent on the mechanical movement speed of the magnetic beads, which is limited by drag force. 
 
 | 
|  | 49. | This can be plugged into the equation in Drag ( physics ) to get you an equation relating speed to the drag force. 
 
 | 
|  | 50. | This is determined by the grains downward acting weight force being matched by a combined buoyancy and fluid drag force and can be expressed by:
