Question

Volume of water dv entering the well, when the head recuperates by dh is ___________

(a) dV=A/dh

(b) dV=A.dh

(c) dV=Khdt

(d) dV=K.A

This question was addressed to me in an interview for internship.

The above asked question is from Well Hydraulics topic in chapter Well Hydraulics of Geotechnical Engineering I

Answer 1

Right answer is (b) dV=A.dh

The explanation: Volume of water entering the well, when the head recuperates by dh is given by the equation: dV=Adh

Where, A=cross-sectional area of the well at its bottom.
