Question

If hydraulic gradient becomes zero, then discharge will be

• A. Maximum
• B. Minimum
• C. Zero
• D. Infinite

Hint:

Darcy's Law: \[ \boxed{Q=KiA} \] If \[ \boxed{i=0} \] then \[ \boxed{Q=0.} \]

Answer 1

The Correct Option is C

According to Darcy's Law, \[ Q=KiA \] where \(Q\) is the discharge, \(K\) is the hydraulic conductivity, \(i\) is the hydraulic gradient, and \(A\) is the cross-sectional area. If the hydraulic gradient is zero, \[ i=0 \] then \[ Q=K(0)A=0. \] Hence, \[ \boxed{\text{Zero}} \] is the correct answer. Therefore, \[ \boxed{(C)} \]
