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)
\[
v_{N}=\frac{C_{w}}{\sqrt{t}}
\]
