engineering recuitment PPSC JE Civil Mock Test 2022 Fluid Mechanics Open Channel Flow Gradually Varied
A rectangular open channel carries a discharge of 15 cumecs at depth of flow of 1.5 m and bed slope as 1:1440. If the only slope is changed to 1:1000 with the same depth of flow, discharge will be:-
1
21.6 cumecs
2
18.0 cumecs
3
14.4 cumecs
4
12.5 cumecs
