Formula 5.91

Laminar flow along a flat plate (approximate solution)

Input(s)

$\mathrm{v} \infty$: Fluid Velocity $(\mathrm{ft} / \mathrm{s})$

L: Length of Plate $(\mathrm{ft})$

W: Width of Plate $(\mathrm{ft})$

$\rho$: Density of Fluid $(\mathrm{g} / \mathrm{cc})$

$\mu$: Viscosity $(\mathrm{cP})$

Output(s)

$\boldsymbol{F}_{\boldsymbol{x}}$: Momentum Flux (psi)

Formula(s)

$$ \mathrm{F}_{\mathrm{x}}=1.293 *\left(\left(\rho * \mu * \mathrm{~L} *\left(\mathrm{~W}^{2}\right) *\left(\mathrm{v}_{\infty}^{3}\right)\right)^{0.5}\right) $$
