η_T = (T₃-T₄)/(T₃-T_4,s)
This formula uses 4 Variables

Variables Used

Efficiency of Turbine - Efficiency of Turbine is the ratio of work obtained from turbine to the heat supplied to turbine.
Turbine Inlet Temperature - (Measured in Kelvin) - Turbine Inlet Temperature refers to the temperature of the fluid entering a turbine, such as the hot gases from combustion in a gas turbine engine.
Turbine Exit Temperature - (Measured in Kelvin) - Turbine Exit Temperature is the flow temperature after expanding through the turbine.
Isentropic Turbine Exit Temperature - (Measured in Kelvin) - Isentropic Turbine Exit Temperature is the temperature of the fluid leaving a turbine under isentropic (reversible adiabatic) conditions.

STEP 1: Convert Input(s) to Base Unit

Turbine Inlet Temperature: 1300 Kelvin --> 1300 Kelvin No Conversion Required
Turbine Exit Temperature: 600 Kelvin --> 600 Kelvin No Conversion Required
Isentropic Turbine Exit Temperature: 525 Kelvin --> 525 Kelvin No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

η_T = (T₃-T₄)/(T₃-T_4,s) --> (1300-600)/(1300-525)

Evaluating ... ...
