(0.7+0.3)/2=0.5.
0.5*10=5.
0.5*10=5.

Velocities by current meter=0.7 and 0.3m.
Taking average velocity=0.7+0.3/2=0.5m/s.
Now,
We know that,
Q=Area x velocity,
Here velocity= average velocity =0.5m/s,
Area = depth x breadth of channel,
Taking width as b=1m.
Area= 10 x 1=10metre square.
Now Discharge=10 x 0.5=5 cubic metre/sec.
We know that discharge intensity or discharge per unit width =Q/b =5/1= 5ans.
Hope helped.
