A well fully penetrates a confined aquifer 10 m thick with k = 20 m/day. The drawdowns at 10 m and 100 m from the well differ by 1 m. By Thiem's equation, the discharge is about:
सही उत्तर: ख) 546 m³/day
Q = 2πkb(s1 − s2)/ln(r2/r1) = 2π × 20 × 10 × 1/ln10 ≈ 1256.6/2.303 ≈ 546 m³/day.

Earthwork is computed by the trapezoidal (average end area) formula and by the prismoidal formula for the same sections. The prismoidal correction is:
सही उत्तर: घ) Subtracted from the trapezoidal volume, since the trapezoidal method generally overestimates
For cuttings and embankments the end area method usually gives more volume than the prismoidal formula, so the prismoidal correction is deducted.
