Question

The sinking of the dredge is uniform in which of the following, shapes of well?

(a) Double-D

(b) Rectangular

(c) Circular

(d) Dumb-well

I got this question by my college professor while I was bunking the class.

My enquiry is from Shapes of Wells and Component Parts in chapter Well Foundations of Geotechnical Engineering II

Answer 1

Correct choice is (c) Circular

To explain I would say: As the perimeter of the circle is equidistant at all points from the center of the dredge hole, the sinking is more uniform than other shapes.
