Lacey's equation for calculating flood discharge in rivers, is
A
$${\text{V}} = 10.8\,{{\text{R}}^{\frac{1}{2}}}{{\text{S}}^{\frac{1}{2}}}$$
B
$${\text{V}} = 10.8\,{{\text{R}}^{\frac{2}{3}}}{{\text{S}}^{\frac{1}{2}}}$$
C
$${\text{V}} = 10.8\,{{\text{R}}^{\frac{2}{3}}}{{\text{S}}^{\frac{1}{3}}}$$
D
$${\text{V}} = 10.8\,{{\text{R}}^{\frac{1}{3}}}{{\text{S}}^{\frac{2}{3}}}$$
Correct Answer: $${\text{V}} = 10.8\,{{\text{R}}^{\frac{2}{3}}}{{\text{S}}^{\frac{1}{3}}}$$
