Filter cake on the fracture (acidizing)

Input(s)

$C_{w}$: Fluid Loss Coefficient, $\left(\mathrm{m} / \mathrm{s}^{1 / 2}\right)$

$\sqrt{t}$ : Time root $\left(\mathrm{s}^{1 / 2}\right)$

Output(s)

$v_{N}$: Fluid Loss Velocity $(\mathrm{m} / \mathrm{s})$

Formula(s)

$$ v_{N}=\frac{C_{w}}{\sqrt{t}} $$
