Turbine Static Efficiency

Turbine static efficiency, abbreviated as PSE, a dimensionless number, is efficiency under steady state or static conditions when converting fluid energy into mechanical or electrical energy.  It is a measure of how effectively the turbine converts the energy in the fluid into useful output power.   The static efficiency provides an indication of how well the turbine is performing under steady state conditions.  A higher static efficiency indicates that a larger percentage of the energy in the fluid is being effectively converted into useful power.  Various factors, including turbine design, operating conditions, and losses, can influence the static efficiency of a turbine.

 

Turbine Static Efficiency formula
\( TSE =  ( P_o \;/\; P_i ) \; 100 \)     (Turbine Static Efficiency) \( P_o =   TSE \; P_i \;/\; 100 \) \( P_i =   P_o \; 100 \;/\; TSE \)

\( TSE \) = turbine static efficiency	\(dimensionless\)
\( P_o \) = output turbine power	\(W\)	\(kg-m^2 \;/\; s^3\)
\( P_i \) = input turbine power	\(W\)	\(kg-m^2 \;/\; s^3\)
