Fluid kinetic force in flow around submerged objects

Input(s)

R: Radius of Sphere (ft)(\mathrm{ft})

ρ\rho: Density of Fluid (lb/ft3)\left(\mathrm{lb} / \mathrm{ft}^{3}\right) v: Velocity of Fluid (ft/s)

f: Friction Factor (dimensionless)

Output(s)

Fk\boldsymbol{F}_{\boldsymbol{k}}: Fluid Kinetic Force (N)

Formula(s)

Fk=π0.5(R2)ρ(v2)f\mathrm{F}_{\mathrm{k}}=\pi * 0.5 *\left(\mathrm{R}^{2}\right) * \rho *\left(\mathrm{v}^{2}\right) * \mathrm{f}
