A gas turbine combustor receives air at s1=6.83 kJ/kg⋅Ks_1 = 6.83 \text{ kJ/kg}\cdot\text{K} and fuel with negligible mass flow rate. The products exit at s2=7.45 kJ/kg⋅Ks_2 = 7.45 \text{ kJ/kg}\cdot\text{K} with mass flow rate 4.2 kg/s4.2 \text{ kg/s}. Heat is lost to the surroundings at 15 kW15 \text{ kW} to ambient at 300 K300 \text{ K}. The combustion provides 2800 kW2800 \text{ kW} of energy. What is the entropy generation rate?
