2) In the figure a rectangular horizontal canal is given where v-2 m/s, h=2m, B-5m, B, 6.9m and B, 4m. What would be the depths of the flow in the narrow (section 1 and 3) and expanded (section 2) sections. Energy loss would be taken into consideration which is given by AH = K (V-V) 2g for expanding section, and K=0.1 for narrowing section and ena gy loss is given by KV where K=0.82 flow! B=5m 6=6.9m DH-3 B3=4.0m 3 = KV 29 AH-2 = K. (V-V ) 29 ANSWER: h2 = 2.09m, h3 = 1.77m
