WebI was asked to calculate the drag force on a cone with velocity 10 m/s, everything was okay until I needed to calculate the cross sectional area, the radius of the base was 0.5 m, radius of the top 0. ... and if you are using the drag equation \begin{align} F_\mathrm{drag} = \frac{1}{2}C_d\rho Av^2 \end{align} to compute the drag force, then ... WebRequiring the force balance F d = F g and solving for the velocity v gives the terminal velocity v s. Note that since the excess force increases as R 3 and Stokes' drag …

WebThe viscosity coefficient can be calculated using the Stokes' Law equation: π η F = 6 π r η v where F is the viscous drag force on the sphere, r is the radius of the sphere, η is the viscosity coefficient of the liquid, and v is the velocity of … WebThe drag force is given as: D = C d ∗ ρ ∗ V 2 A 2 D = 0.25 ∗ 1.2 ∗ 6400 ∗ 6 2 ∗ 3600 D=1.6 N Question 2. A plane moves with the velocity of 600 km.h -1 with a drag coefficient of … Webperturbational velocity. The momentum equation needed to replace the Stokes equation contains the term U∂u ∂x. We shall remark on the need for the Oseen system later in connection with two-dimensional Stokes flow. 7.1 Solution of the Stokes equations Returning to dimensional equations, the Stokes equations are ∇p− µ∇2u = 0, ∇·u ... dbs check evidence
