1. What is the Brayton Cycle Power Equation?

The Brayton Cycle Power Equation calculates the net power output of a gas turbine engine based on mass flow rate, specific heat capacity, and temperature differences across the turbine and compressor components.

2. How Does the Calculator Work?

The calculator uses the Brayton cycle power equation:

Where:

• \( \dot{m} \) — Mass flow rate (kg/s)
• \( c_p \) — Specific heat capacity (J/kg K)
• \( T3 \) — Turbine inlet temperature (K)
• \( T4 \) — Turbine exit temperature (K)
• \( T2 \) — Compressor exit temperature (K)
• \( T1 \) — Compressor inlet temperature (K)

Explanation: The equation calculates the net work output by considering the work produced by the turbine minus the work consumed by the compressor.

3. Importance of Power Calculation

Details: Accurate power calculation is essential for designing and analyzing gas turbine engines, optimizing performance, and determining efficiency in various engineering applications.

4. Using the Calculator

Tips: Enter all temperature values in Kelvin, mass flow rate in kg/s, and specific heat capacity in J/kg K. All values must be positive and valid.
