1. What is the Well Function Given Constant Dependent On Well Function And Chow's Function?

The Well Function given constant dependent on well function and Chow's function is a mathematical relationship used in hydrogeology to analyze drawdown data in pumping tests. It helps determine aquifer characteristics and well performance.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Wu = \frac{2.303 \times Fu}{\exp(u)} \]
