Question 6
Direction: Each of the following items consists of two statements, one labelled as the ‘Statement (I)’ and the other as ‘Statement (II)’. Examine these two statements carefully and select the answers to these items using the codes below:
Statement (I): Open channel flow in a channel is said to be critical when the specific force is maximum for a given discharge.
Statement (II): Direct integration for steady non-uniform flow by Bresse’s method was developed for very wide rectangular channels.
Statement (II): Direct integration for steady non-uniform flow by Bresse’s method was developed for very wide rectangular channels.
