5: Answer the following:
A- A drain of rectangular shape, b= 5.4 m, d 1.2 m, S= 1* 10. Resize a new dimension for the drain so that it
can carry a larger discharge up to 7 m³/sec. Also calculate the percentage of the increase in discharge, use n= 0.035.
B- A semi-modular pipe outlet of diameter 25 cm is to be installed on a distributary with its bed level and full
supply level at 100.3 m and 102 m, respectively. The maximum water level in the watercourse is at 101.25 m. Set
the outlet for maximum discharge and calculate it. The coefficient C in the discharge equation may be taken as 0.62.
What is the behaviour of this setting? Take m=1/2, n=5/3.
