Water Yield (\( Q = \frac{\pi K (H^2 - h^2)}{\log_e \frac{R}{r}} \)):

Where:

• \( Q \) is the rate of flow, in cubic feet per day (ft³/day).
• \( K \) is the hydraulic conductivity.
• \( H \) is the height of the static water level above the bottom of the water-bearing formation, in feet (ft).
• \( h \) is the height of the water level at the well measured from the water-bearing formation, in feet (ft).
• \( R \) is the radius of influence, in feet (ft).
• \( r \) is the radius of the well, in feet (ft).
