The efficiency is a measure of conservation of head by an outlet.

True

False

182.

The sensitivity of an outlet is defined as the ratio of the

A.	rate of change of discharge of an outlet to the rate of change of discharge of the distributing channel	B.	rate of change of discharge of an outlet to the rate of change in level of the distributing surface, referred to normal depth of the channel
C.	depth of the sill or the crest level of the module below the full supply of the distributing channel to the full supply depth of the distributing channel	D.	head recovered to the head put in an outlet

183.

An outlet is said to be proportional, if its flexibility is

A.	equal to zero	B.	less than unity
C.	equal to unity	D.	more than unity

184.

The sensitivity of a rigid module is

A.	equal to zero	B.	less than unity
C.	equal to unity	D.	more than unity

185.

The flexibility of a hyper-proportional outlet is

A.	greater than	B.	equal to
C.	less than

186.

The flexibility of a sub-proportional outlet is less than one

Yes

187.

The setting of an outlet is defined as the ratio of the

A.	rate of change of discharge of an outlet to the rate of change of discharge of the distributing channel	B.	rate of change of discharge of an outlet to the rate of change in level of the distributing surface, referred to normal depth of the channel
C.	depth of the sill or the crest level of the module below the full supply of the distributing channel to the full supply depth of the distributing channel	D.	head recovered to the head put in an outlet

188.

For the pipe outlet to be proportional, the outlet is set at

A.	0.3 times	B.	0.5 times
C.	0.8 times

189.

In the case of a proportional outlet, the setting is equal to the ratio of outlet index to the channel index.
