The channel slope is . Find the water velocity and the flow rate. I V n JR2 3 2 from Table A-13 R A p m V 2 3 m s Q Av 178 m3 s Water flows in the symmetrical trapezoidal channel lined with asphalt shown in Fig. 14-1. The channel bottom drops ft vertically for every 100 ft of length. What are the water velocity and flow rate f V 7 2 3 s1 2 from Table A-13 R A p A 2 3 2 ft2 p 2V 2 3 2 ft R ft s 100 V 2 1 2 ft s Q Av 863 ft3 s Water is to flow at a rate of 30 m3 s in the concrete channel shown in Fig. 14-2. Find the required vertical drop of the channel bottom per kilometer of length. f A - 2 m2 V n 2 3 s1 2 Q A 30 m s Ph V - 2 - 2 m R A pw m 2 3 s 1 2 5 This slope represents a drop of the channel bottom of m per meter of length or m per kilometer of length. 356 FLOW IN OPEN CHANNELS Ũ 357 Water flows in the triangular steel channel shown in Fig. 14-3 at a velocity of ft s. Find the depth of flow if the channel slope is . f V n K2 3 s1 2 R A pw 2 d d tan 2 2d cos 2 3 1 2 d ft Fig. 14-3 14J After a flood had passed an observation station on a river an engineer visited the site and by locating flood marks performing appropriate surveying and doing necessary computations determined that the cross-sectional area wetted perimeter and water-surface slope at the time of the peak flooding were 2960 m2 341 m and respectively. The engineer also noted that the channel bottom was earth with grass .
