Pick out the correct equation.

A $${\text{JH}} = \left( {{\text{St}}} \right){\left( {{\text{Pr}}} \right)^{\frac{2}{3}}} = \frac{{\text{f}}}{2}$$
B $${\text{JH}} = \left( {{\text{St}}} \right){\left( {{\text{Pr}}} \right)^{\frac{1}{3}}} = \frac{{\text{f}}}{2}$$
C $${\text{JH}} = {\left( {{\text{St}}} \right)^{\frac{2}{3}}}\left( {{\text{Pr}}} \right) = \frac{{\text{f}}}{2}$$
D $${\text{JH}} = {\left( {{\text{St}}} \right)^{\frac{1}{3}}}\left( {{\text{Pr}}} \right) = \frac{{\text{f}}}{2}$$

Correct Answer: $${\text{JH}} = \left( {{\text{St}}} \right){\left( {{\text{Pr}}} \right)^{\frac{2}{3}}} = \frac{{\text{f}}}{2}$$
