Question

How many types of submerged pipe outlets can be laid?

(a) 2

(b) 3

(c) 4

(d) 5

This question was posed to me during an interview for a job.

My query is from Regulation Modules in portion Regulation Modules and Canal Structure of Irrigation Engineering

Answer 1

Right answer is (a) 2

To elaborate: The submerged pipe outlets can be laid either horizontally or sloping upwards. Generally, they are embedded in concrete and fixed horizontally at right angles to the direction of flow. They can also be laid sloping upwards to increase the silt conductivity.
