Rankine cycle efficiency calculator:
This Rankine Cycle Efficiency Calculator is used to find the thermal efficiency of steam power cycles. Input boiler and condenser pressures, turbine inlet temperature, and optional superheat to calculate work output, heat input and cycle efficiency in step-by-step calculation.
Rankine cycle efficiency Tool Formula:
First Law of Thermodynamics:
\[ \textrm{Efficiency } (\eta) = 1 - \frac{Tc}{Th} \]
Rankine Cycle Efficiency Calculator is a tool used by engineers, students and researchers to calculate thermal efficiency of power plant steam power cycles. Rankine cycle is common in steam turbines and is the ideal cycle of boiler, turbine, condenser and pump.
The user is able to key in boiler pressure, condenser pressure, turbine inlet temperature and optionally superheat or reheat settings. Through the calculator, the thermal efficiency η, work output of turbine, work of pump, heat input and net work is calculated, using standard Rankine cycle formulas. The conversion of energy in each of the components is described in step-by-step solutions, and it is therefore easy to analyze ideal and real-world processes in steam power plants, industrial turbines, and thermal engineering applications.
SI units are accepted: kPa, MPa, o C, K, kJ/kg, MW. Mechanical engineers, thermal engineers, power plant engineers, and students will find this tool appropriate because it will provide the right way of energy analysis and performance evaluation of Rankine cycles and steam turbines.
⚡ Work & Installation Input to Output:
Input:
- Boiler pressure (P_boiler)
- Condenser pressure (P_condenser)
- Turbine inlet temperature (T_in)
- Optional: superheat or reheat parameters
- Units: kPa, MPa, °C, K, kJ/kg
Processing:
- Compute turbine work output using enthalpy drop: W_turbine = h1 – h2
- Compute pump work: W_pump = h4 – h3
- Compute heat added in boiler: Q_in = h1 – h4
- Compute thermal efficiency: η = (W_turbine – W_pump) / Q_in
- Validate input values and unit consistency
Output:
- Thermal efficiency (η)
- Turbine work output (W_turbine)
