The top width and the top depth of flow in a triangular channel were measured as $4$ m and $1$ m, respectively. The measured velocities on the centre line at the water surface, $0.2$ m and $0.8$ m below the surface are $0.7$ m/s, $0.6$ ... Using two-point method of velocity measurement, the discharge (in $m^3/s$) in the channel is $1.4$ $1.2$ $1.0$ $0.8$
