Rate of Flow (\( q \)):

\[ q = \frac{2 \pi K d (H - h)}{\log_e \frac{R}{r}} \]

Where:

• \( q \) is the rate of flow, in cubic meters per second (m³/s).
• \( K \) is the hydraulic conductivity, in meters per second (m/s).
• \( d \) is the thickness of the confined layer, in meters (m).
• \( H \) is the height of the static piezometric surface above the top of the water-bearing formation, in meters (m).
• \( h \) is the height of the water in the well above the top of the water-bearing formation, in meters (m).
• \( R \) is the radius of influence, in meters (m).
• \( r \) is the radius of the well, in meters (m).
