Drainage slide rule
Pocket sized agricultural drainage calculator enables the user to:
- compute required pipe size for given drainage area;
- compute acres drained for given pipe size/grade;
- estimate permissible flow velocities for any pipe size, based on grade;
- compute flowrates for pipe sizes/grades. Features of the calculator are: functionality for both corrugated and smooth-wall materials, roughness coefficients are built-in, other design and look-up tables are included.
