If the coefficient of discharge is 0.6, then the discharge over a right angled notch is
A. $$0.417\,{{\text{H}}^{\frac{5}{2}}}$$
B. $$1.417\,{{\text{H}}^{\frac{5}{2}}}$$
C. $$4.171\,{{\text{H}}^{\frac{5}{2}}}$$
D. $$7.141\,{{\text{H}}^{\frac{5}{2}}}$$
Answer: Option B

8/15 * C * [(2g)^1/2] * (H^5/2).
C = coefficient of discharge
Could you tell me what is the value of g
