STEP 1: Convert Input(s) to Base Unit

Velocity of Flow at Radial Distance: 15 Centimeter per Second --> 0.15 Meter per Second (Check conversion here)
Change in Radial Distance: 0.25 Meter --> 0.25 Meter No Conversion Required
Coefficient of Permeability: 3 Centimeter per Second --> 0.03 Meter per Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

dh = V_r*dr/K --> 0.15*0.25/0.03

Evaluating ... ...

dh = 1.25

STEP 3: Convert Result to Output's Unit

1.25 Meter --> No Conversion Required

FINAL ANSWER

1.25 Meter <-- Change in Piezometric Head
