Geometry parameters of dichotomous tree-like networks

Generation	The number of branches	Diameter (μm)	Vessel volume (ml)
0	1	200	0.519(–)/1
1	2	100	0.296(–)/2
2	4	80	0.074(–)/4
3	8	60	0.037(–)/8
4	16	40	0.022(–)/16
5	32	20	0.022(–)/32
6	64	10	0.030(–)/64
7	128	5.95 or 6.13	/128

The diameter of capillaries, i.e. generation 7, is chosen to be 5.95 μm for LZRs, and 6.13 μm for OZRs. and , denoting the overall volume and the capillary volume of the i^th SVN, respectively, are determined from eqns (18) and (20).
