Δs D = 2.3 \cdot \frac{7m³/s}{11m²/s \cdot 2 \cdot π}

Next Step Substitute values of Constants

∴

Δs D = 2.3 \cdot \frac{7m³/s}{11m²/s \cdot 2 \cdot 3.1416}

Next Step Prepare to Evaluate

∴

Δs D = 2.3 \cdot \frac{7}{11 \cdot 2 \cdot 3.1416}

Next Step Evaluate

∴

Δs D = 0.232944962161774

LAST Step Rounding Answer

∴

Δs D = 0.2329

Variables

Constants

Drawdown Across Log Cycle

The Drawdown Across Log Cycle is referred as change in water level (or hydraulic head) in an aquifer due to pumping from a well.

Symbol: Δs_D

Measurement: NAUnit: Unitless

Note: Value can be positive or negative.

Pumping Rate

The Pumping Rate is referred as volume of water (or other fluid) that is pumped per unit of time. It’s typically measured in units like liters per second (L/s) or cubic meters per hour (m³/h).

Symbol: q

Measurement: Volumetric Flow RateUnit: m³/s

Note: Value can be positive or negative.

Transmissivity

Transmissivity is the rate at which groundwater flows horizontally through an aquifer or the degree to which a medium allows something, in particular electromagnetic radiation, to pass through it.

Symbol: T

Measurement: Kinematic ViscosityUnit: m²/s

Note: Value can be positive or negative.

Archimedes' constant

Archimedes' constant is a mathematical constant that represents the ratio of the circumference of a circle to its diameter.

Symbol: π

Value: 3.14159265358979323846264338327950288
