Formula 2.14

API water loss calculations

Input(s)

$\mathrm{V}_{\mathrm{a}}$: Water Loss in $7.5 \mathrm{~min}\left(\mathrm{~cm}^{3}\right)$

$\mathrm{V}_{\mathrm{sp}}$: Spurt Loss $\left(\mathrm{cm}^{3}\right)$

Output(s)

$\mathrm{V}_{30}$: Water Loss $\left(\mathrm{cm}^{3}\right)$

Formula(s)

$$ \mathrm{V}_{30}=\left(2 * \mathrm{~V}_{\mathrm{a}}\right)-\left(\mathrm{V}_{\mathrm{sp}}\right) $$
