Filtration rate for API fluid loss measurement
Input(s)
\(h_{m c}\): Filter Cake Thickness \((\mathrm{cm})\)
\(A\): Filter Cake Area \(\left(\mathrm{cm}^{2}\right)\)
\(\Delta P\): Pressure Difference (Atm)
\(k\): Permeability of the Filter Cake (D)
\(\mu\): Viscosity of the Filtration Fluid (cP)
Output(s)
\(\frac{d V_{f}}{d t}\): Filtration Rate \((\mathrm{cc} / \mathrm{s})\)
Formula(s)
\[
\frac{\mathrm{dV}_{\mathrm{f}}}{\mathrm{dt}}=\frac{\mathrm{k} \cdot \mathrm{A} \cdot \Delta P}{\mu \cdot \mathrm{h}_{\mathrm{mc}}}
\]
