UMich CSS benchmark model

Vacuum tubing benchmark

Use acreage and tap density to sketch a conservative vacuum tubing system before you draw the real layout.

Calculator

Based on the UMich CSS model: square sugarbush, uniform tap density, 5/16 inch laterals, and leakage load per 100 taps.

How it works

The model treats the sugarbush as a square with uniform tappable tree density. It estimates tap count, groups taps into laterals, sizes a practical number of mainlines, and applies the common 1.0-1.5 CFM leakage load per 100 taps. Treat the result as a planning benchmark, not an as-built design.
