WebFeb 3, 2024 · Resistance to motion of a body in a fluid due to forces of friction being exerted between the body and the fluid. Fluid resistance is directly proportional to the cross-sectional area of a body at right angles to the motion, and directly proportional to the square of the velocity of the body relative to the fluid. See also drag. WebMay 30, 2024 · Based from the figure above, there are only two forces acting on it: (1) the force mainly responsible for the fall: gravitational attractive force between the falling object and Earth, Fg (or weight) and (2) the force resisting the motion which is fluid resistance (liquid or gas), Ff. earth seasons diagramWebQuestion: a. The generalized force, denoted as Q(Φ), with respect to the resistance of the fluid to the acceleration of the cylinder, considering the angle Φ between the cylinder axis and the vertical direction, can be written as follows:Q(Φ) = ∫[2ρπfluid R L a z(Φ) dz]where a z(Φ) is the linear acceleration of the fluid element at height z along the cylinder earthsea trilogy map

"WebNov 21, 2016 · The equation for viscous resistance or linear drag is appropriate for objects or particles moving through a fluid at relatively slow speeds where there is no turbulence (i.e. low Reynolds number, $\displaystyle R_{e}<1$).
