Underdrain System Discharge Calculator
Calculate the discharge of an underdrain system using the formula:
\(\displaystyle Q = \frac{K_s \times A_d \times (H_{in} – H_{out})}{L_d}\)
* Enter the hydraulic conductivity \(K_s\) (ft/day), effective underdrain area \(A_d\) (ft²), inlet head \(H_{in}\) (ft), outlet head \(H_{out}\) (ft), and flow length \(L_d\) (ft).
Step 1: Enter Parameters
Example: 2.0 ft/day
Example: 50 ft²
Example: 10 ft
Example: 2 ft
Example: 20 ft
