A rectangular suppressed weir is a device used to measure stream flow in an open channel. For a rectangular suppressed weir flowing free, the discharge Q is related to the head H over the weir as _________.
1
Q = \(\rm\frac{2}{3} C_{d} \sqrt{2 g} LH ^{\frac{1}{2}}\)
2
Q = \(\rm\frac{8}{15} C_{d} \sqrt{2 g} H ^{\frac{3}{2}}\)
3
Q = \(\rm\frac{2}{3} C_{d} \sqrt{2 g} H ^{\frac{3}{2}}\)
4
Q = \(\rm\frac{2}{3} C_{d} \sqrt{2 g} H ^{\frac{2}{3}}\)
