Find the terminal velocity of an 85-kg skydiver falling in a spread-eagle position. Strategy At terminal velocity, Fnet = 0. Thus the drag force on the skydiver must equal the force of gravity (the person’s weight). Using the equation of drag force, we find mg=12ρCAv2mg=12ρCAv...
Jingyi Zhao, in Ocean Engineering, 2022 Drag force For slender columns, the influence of the drag force on the platform can be calculated by the Morison equation, and the drag force per unit length of column is (A-26)fD=12ρCDD(wx−x˙)|(wx−x˙)| where: D is the diameter of...
The drag equation calculator helps you compute a force exerted on a moving object immersed in a fluid. Reading the text below, you will discover what the equation for drag force is, how the shape of the object influences the force and what the drag coefficient is. What is the equation for...

With Cf,lamas the overall friction drag coefficient, the wall shear stress in equation (11) refers to the entire surface area A of the plate (mean wall shear stress τw). Thus, the acting frictional force Ff,lamon this surface can be calculated using the following formula: ...
On account of the thinness of the wake, we can neglect, in the integral over the plane x = x1, the integral over the cross-section of the wake, and so integrate only over the region outside the wake. In that region, however, we have potential flow, and Bernoulli's equation p + 1...
container filled halfway with water, the air is the dispersed phase in the bottom half of the container; in the top half of the container, the air is the continuous phase.（4） Select wen-yu to use the fluid-solid drag function described by Equation 20.4-40.The Wen and Yu...

The drag force was estimated according to the equation of motion "ma = Fp + Fd" along with swimming direction. The elite swimmer swam efficiently with lower drag force (averaging at 21N) compared to the non-elite swimmer (average 50N). Our methodology would be useful to compare the ...
Furthermore, frictional resistance is a force that occurs due to the interaction between a liquid (in this case, water), and a solid surface. Park and Sun15 investigated frictional drag on the air–water interface. However, accurately measuring frictional resistance can be challenging. Various ...
