Question

According to Dupuit’s theory,the velocity of flow is proportional to__________

(a) Sine of hydraulic gradient

(b) Tangent of hydraulic gradient

(c) None of the mentioned

(d) All of the mentioned

I got this question by my school principal while I was bunking the class.

The query is from Well Hydraulics in section Well Hydraulics of Geotechnical Engineering I

Answer 1

Right option is (b) Tangent of hydraulic gradient

Explanation: Based on the assumption proposed by Dupuit’s theory, the velocity of flow is proportional to the tangent of the hydraulic agent instead of its sine.
