The overall efficiency of a turbine is dependent on the hydraulic loss, volumetric losses and mechanical losses represented by various efficiencies. These related to overall efficiency as
1
\(\frac{{{\eta _h} + {\eta _v} + {\eta _m}}}{3}\)
2
\({\left( {{\eta _h}{\eta _v} \cdot {\eta _m}} \right)^{\frac{1}{3}}}\)
3
\({\eta _h} \cdot {\eta _v} \cdot {\eta _m}\)
4
\(\sqrt {{\eta _h} \cdot {\eta _v} \cdot {\eta _m}}\)
