ENGR5003 Lecture 4, slide 9 (Steady flow energy equation - gas turbines)

In a gas turbine, the turbine produces work mainly because:

Formulas you may need

Adiabatic turbine, KE and PE neglected (SFEE): $w_t = h_3 - h_4 = c_p(T_3 - T_4)$ (on the formula sheet)

AThe gas is compressed inside the turbineBHigh-temperature, high-pressure gas expands through the turbineCHeat is transferred directly from the turbine blades to the surroundingsDThe compressor supplies work to the turbine
