Water discharges from an irrigation pond (water surfaceelevation 230 ft) through a 4 ft diameter circular orifice. Theinvert elevation of the orifice is at 213 ft and the bottom of thepond has an elevation of 205 ft. Assuming a Cd = 0.60, calculatethe discharge under two conditions:
a) calculate the discharge if the downstream water height is210 ft.
b) calculate the discharge if the downstream water height is219 ft.
