Rankine Cycle Efficiency

Introduction to Rankine Cycle Efficiency

The Rankine cycle is used in thermal power stations and is the ideal thermodynamic cycle for vapor power plants. The Rankine cycle efficiency, represented by η, is a measure of the efficiency of the Rankine cycle in converting heat into work. The formula calculates the efficiency by dividing the net work heat input, represented by W_net, by the heat supplied at constant pressure, represented by Q_in. The result is rounded to two decimal places.

Parameter usage:

• netWorkHeatInput = net work heat input in kilojoules
• heatSuppliedAtConstantPressure = heat supplied at constant pressure in kilojoules

Example valid values:

• netWorkHeatInput = 5000 kJ
• heatSuppliedAtConstantPressure = 6000 kJ

Output:

• η = Rankine cycle efficiency

Data validation

The numbers should be positive and within the valid range of the Rankine cycle parameters.

Summary

This formula calculates the efficiency of the Rankine cycle, crucial for assessing the performance of vapor power plants.
