Question 31
Open questionCEMCQ2 marksNeeds review
A rectangular open channel of 6 m width is carrying a discharge of 20 m
/s. Consider the acceleration due to gravity as 9.81 m/s
and assume water as incompressible and inviscid. The depth of flow in the channel at which the specific energy of the flowing water is minimum for the given discharge will then beYour answerChoose one option.
