A rectangular channel 6 m wide and 3 m deep and having a bed slope as 1 in 2000 is running full. If Chezy's constant C = 54.8, pick up the correct specification of the channel from the following :

hydraulic mean depth = 1.5 m

Velocity of flow = 1.5 m/sec

Rate of flow = 27 m³/sec

All the above.

If S is the length of the crest, H is the height of water source of a weir whose length is L and discharge is Q m³/sec, the velocity of approach V_d is

\(\sqrt{2gH}\)

\(\frac { Q } { L(H-L) } \)

\(\frac { Q } { L(H+S) } \)

\(\frac { L(H+S )} { Q } \)

none of these.
