Well Pumping Rate Calculator

Calculate sustainable well yield using Thiem equation for steady state: Q = 2πKb(h₂-h₁)/ln(r₂/r₁). Theis equation for transient conditions. Specific capacity and well efficiency from pumping tests.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.

How It Works

Calculate sustainable well yield using Thiem equation for steady state: Q = 2πKb(h₂-h₁)/ln(r₂/r₁). Theis equation for transient conditions. Specific capacity and well efficiency from pumping tests

Each component has a specific meaning:

  • Thiem equation — The thiem equation recorded for the patient or scenario being assessed.

Note: Interpret the well pumping rate result against the clinical thresholds and context described above.

How to Use

Enter the Thiem equation for the patient or scenario you are assessing. Calculate sustainable well yield using Thiem equation for steady state: Q = 2πKb(h₂-h₁)/ln(r₂/r₁). Theis equation for transient conditions. Specific capacity and well efficiency from pumping tests. Use the well pumping rate result to inform your clinical assessment.
