dr = K*dh/V_r
This formula uses 4 Variables

Variables Used

Change in Radial Distance - (Measured in Meter) - Change in Radial Distance is the variation in distance from a pumping well to a specific point in an aquifer over time.
Coefficient of Permeability - (Measured in Meter per Second) - Coefficient of Permeability is the measure of the ability of a porous material (such as soil or rock) to transmit fluids through it. It quantifies how easily water can flow through the material.
Change in Piezometric Head - (Measured in Meter) - Change in Piezometric Head is the difference in hydraulic head between two points within an aquifer or groundwater system.
Velocity of Flow at Radial Distance - (Measured in Meter per Second) - Velocity of Flow at Radial Distance is the speed at which groundwater moves through a porous medium at a specific radial distance from a well or other point of interest.

STEP 1: Convert Input(s) to Base Unit

Coefficient of Permeability: 3 Centimeter per Second --> 0.03 Meter per Second (Check conversion here)
Change in Piezometric Head: 1.25 Meter --> 1.25 Meter No Conversion Required
Velocity of Flow at Radial Distance: 15 Centimeter per Second --> 0.15 Meter per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

dr = K*dh/V_r --> 0.03*1.25/0.15

Evaluating ... ...

dr = 0.25
