A contracted rectangular weir 2 m width was installed in a channel 3-m wide. Water depth elevation upstream of the weir was measured at a distance equal to about 4H upstream of the weir and found to be 2.5 m, the elevation of the weir crest was found2 m, and the acceleration of gravity (g) is given as 9.81. The flow rate of the channel equals to Select one: m'/s A. Q= 1.24 m 3 B. Q= 3.5 m/s C. Q= 7.5 m/s D. Q= 5.24 m /s
