$$( \frac{x}{m} ) = Kp^{(\frac {1}{n})} \text{ ; n ≥ 1}$$
$$\theta = \frac {KP_{\,A}}{1+KP_{\,A}}$$ $$or \frac{m}{x} = \frac{aP}{1+bP}$$ $$or \frac{m}{x} = \frac{1}{aP} + \frac{b}{a}$$
$$\frac{x}{m} = KC^{(\frac{1}{n})}$$ where C is concentration of solute in solution.
$$Z = \frac{4 \pi \eta \mu}{D}$$
