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

Rate of flow = 27 m3/sec
hydraulic mean depth = 1.5 m
All the above.
The flow in a channel is said to be non-uniform, if
head needed to overcome frictional reistance is less than the drop in elevation of channel bed
head needed to overcome frictional resistance is more than the drop in elevation of channel bed
free water surface of an open channel is not parallel to the bed of channel
All the above.
