(Solution) - Products of combustion enter a gas turbine with a stagnation -(2025 Original AI-Free Solution)

Paper Details

Products of combustion enter a gas turbine with a stagnation pressure of 0.75 MPa and a stagnation temperature of 6908C, and they expand to a stagnation pressure of 100 kPa. Taking k = 1.33 and R = 0.287 kJ/kg·K for the products of combustion, and assuming the expansion process to be isentropic, determine the power output of the turbine per unit mass flow.
