Values from regression when Eqs. A8–A11 (diameter-length, volume-length, flow-diameter, and volume-diameter relations, respectively) are represented by Eq. 3. Exponent B is constrained to $\frac{3}{7}$, $1\frac{2}{7}$, $2\frac{1}{3}$, and 3 for Eqs. A8–A11, respectively. SE, standard error; R², correlation coefficient.
