Lacey gave V – Q – f relation as:

A. \({\rm{V}} = {\left[ {\frac{{{\rm{Q}}{{\rm{f}}^2}}}{{160}}} \right]^{\frac{1}{4}}}\)
B. \({\rm{V}} = {\left[ {\frac{{{\rm{Q}}{{\rm{f}}^2}}}{{140}}} \right]^{\frac{1}{6}}}\)
C. \({\rm{V}} = {\left[ {\frac{{{\rm{f}}{{\rm{Q}}^2}}}{{160}}} \right]^{\frac{1}{4}}}\)
D. \({\rm{V}} = {\left[ {\frac{{{\rm{Qf}}}}{{140}}} \right]^{\frac{1}{6}}}\)
Answer» C. \({\rm{V}} = {\left[ {\frac{{{\rm{f}}{{\rm{Q}}^2}}}{{160}}} \right]^{\frac{1}{4}}}\)
