- Allows user to specify maximum allowable bore height;
- Automatically calculates mean hydraulic depth factor and Manning's roughness coefficient;
- Pipe materials covered: asbestos cement, brick, cast-iron, clay, concrete, polyethylene (PE), PVC, steel and more;
- Specify kinematic viscosity of fluid, as default value for water is taken;
- Checks: flow rate running full, design pipe flow, design velocity;
