Question

In cattle crossings, the exact distance to be kept between the two ramps on the same side should theoretically be ________

(a) 2 BV/U

(b) 2 BVU

(c) 2 BU

(d) 2 BU/ V

I have been asked this question in an interview for internship.

My doubt is from Types of Rigid Modules and Cattle Crossings in portion Regulation Modules and Canal Structure of Irrigation Engineering

Answer 1

Correct option is (a) 2 BV/U

The best I can explain: Theoretically, the exact distance to be kept between the two ramps on the same side should be 2 BV / U where, B = width of the channel, V = average flow velocity of water in the channel and U = the speed with which cattle swim. The distance is kept a little longer than shorter even if the cattle reach the opposite side too nearer they will get at the ramp.
