Table A1.

Simplification of equation A18 according to the assumptions in Sections A.1 and A.2 to derive Equations 4 & 5.

${\mathit{r}}_{\mathbf{b}}$	$\mathit{f}$	${\mathit{A}}_{\mathbf{m}}^0$	Comment
0	0	$A_{\mathrm{m}}^0=\frac{A_{\mathrm{d}}\cdot b_{\mathrm{f}}}{m_{\mathrm{f}}(t_{\mathrm{f}})-m_{\mathrm{r}}(t_{\mathrm{d}})}$	Equation 5; no mixing, all evaporation from the drop end.
0-1	1	$A_{\mathrm{m}}^0=\frac{A_{\mathrm{d}}\cdot b_{\mathrm{f}}}{m_{\mathrm{f}}(t_{\mathrm{d}})-m_{\mathrm{r}}(t_{\mathrm{d}})}\cdot \left(1-\frac{m_{\mathrm{f}}(t_{\mathrm{d}})-m_{\mathrm{f}}(t_{\mathrm{f}})}{m_{\mathrm{f}}(t_{\mathrm{f}})-m_{\mathrm{e}}}\right)$	Equation 4; instantaneous mixing.
