Diesel Cycle Heat

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

Q_in = Heat Added (2-3) (J)

Q_out = Heat Rejected (4-1) (J)

m = Mass of the working fluid (kg)

C_p = Specific Heat at Constant Pressure (J/kg K)

C_v = Specific Heat at Constant Volume (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)
