Brayton Cycle Heat Calculator

Heat Added (Q_in):

Heat Rejected (Q_out):

Specific Heat at constant pressure (C_p):

Temperature at state 1 (T₁):

Temperature at state 2 (T₂):

Temperature at state 3 (T₃):

Temperature at state 4 (T₄):

How This Is Calculated

Heat Added: $$ Q_{in} = C_p (T_3 - T_2) $$ Heat Rejected: $$ Q_{out} = C_p (T_4 - T_1) $$ where:

Q_in = Heat Added (J)

Q_out = Heat Rejected (J)

C_p = Specific Heat at constant pressure (J/kg K)

T₁ = Temperature at state 1 (K)

T₂ = Temperature at state 2 (K)

T₃ = Temperature at state 3 (K)

T₄ = Temperature at state 4 (K)

Assumptions

The system is in steady state.
Working fluid is an ideal gas.
Specific heat remains constant.
Compression and expansion processes are adiabatic.
