11.2 Calculating Drag forceEquation, Drag Force
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...
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...
In subject area: Earth and Planetary Sciences Friction drag refers to the resistance experienced by a body moving through a fluid due to the shear force exerted on its surface. It is a component of the total drag force along with pressure drag, and is influenced by factors such as fluid de...
An equation of similar form describes the data in Figure 3.4 (3.8)CD=4.90Φ21/2(1+0.243Φ21/3)+0.4161+3.91×104Φ2−1 Depending on the problem context, the drag coefficient can be calculated from equations 3.3, 3.4, 3.7 or 3.8 and then used with equation 3.1 to calculate the force ...
Alternatively, it can be determined by solving the implicit equation of Rossby similarity assuming a neutral IOBL27: Uiu0∗∝ln(u0∗fz0), where u0∗=τw is the interfacial friction velocity, f is the Coriolis frequency, and z0 is the surface roughness. In the Arctic Ocean, there are...
For multi-phase simulation, single-fluid Navier鈥擲tokes equations, along with the volume fraction transport equation, are employed. The bubble dynamics model is utilized to simulate phase change between vapor and liquid phases of the water. Unsteady simulation of cavitation around NACA66(MOD) and...

Pressure drag refers to the resistance experienced by a body moving through a fluid due to the normal pressure force exerted by the fluid in the direction of flow. It is a component of the total drag force along with skin friction drag. ...
In computer modeling, net drag has been calculated by representing the net threads as cylinders and using a Morison equation approach (Tsukrov et al., 2000). More recent finite element developments include the use of “consistent net elements” which depend on an understanding of fluid dynamic ...
