| Solved for Two Simultaneous Pipe Conditions, on the Same Slope: |
 |
| Insert Your Conditions: | |||
| n1 | Manning's coefficient of the liner pipe | ||
| n2 | Manning's coefficient of the host pipe | ||
| D1 | Inside diameter of the liner pipe | inches | |
| D2 | Inside diameter of the host pipe | inches | |
| Relative Flow: | Q1/Q2 = | ||
| Flow Capacity Recovery*: | = | ||
 |
