Question

If A1 and A2 represent the areas enclosed between two successive contours, then the cubic content between these contours is roughly taken as _________________

(a) (A1 + A2) x h/2

(b) A1.A2 x h/2

(c) A1 x h/2

(d) A2 x h/2

The question was asked during an interview.

This intriguing question comes from Tank Irrigation topic in portion River Navigation & Tank Irrigation of Irrigation Engineering

Answer 1

Right choice is (a) (A1 + A2) x h/2

The explanation is: The cubic content between two successive contours is computed as (A1 + A2) x h/2. The required storage capacity of the tank is the summation of all cubic contents between the successive contours.
