Filtration volume with spurt loss
Input(s)
\(V_{s p}\): Spurt Loss Volume (cc)
\(V_{f 1}\): Filtration Volume at time "1" (cc)
\(V_{f 2}\): Filtration Volume at time "2" (cc)
\(t_{1}\): Time value " 1 " (min)
\(t_{2}\): Time value "2" (min)
\(t\): Filtration time of the measured Filtration Volume " \(\mathrm{V}_{\mathrm{f}}\) " (min)
Output(s)
\(V_{f:} \quad\) Filtration Volume (cc)
Formula(s)
\[
\mathrm{V}_{\mathrm{f}}=\mathrm{V}_{\mathrm{sp}}+\frac{\mathrm{V}_{\mathrm{f} 2}-\mathrm{V}_{\mathrm{f} 1}}{\sqrt{\mathrm{t}_{2}}-\sqrt{\mathrm{t}_{1}}} \sqrt{\mathrm{t}}
\]
