文摘
- •
An analytical formula for the hydraulic resistance of a single root is derived.
- •
Local water-uptake profile in the stele is obtained analytically.
- •
Three-dimensional end effect reduces the hydraulic resistance by as much as 36%.
- •
Hydraulic resistance is generally not the sum of radial and axial resistances.
