You are to evaluate two possible steam turbines that are needed to produce 10 MW of power for a small factory.
Option A: An insulated turbine that receives steam at 1000 kPa and 300°C, has an exit pressure of 30 kPa, and has an exit quality of 0.98
Option B: An uninsulated turbine that receives steam at 4000 kPa and 500°C, exhausts the steam at 50 kPa and a quality of 0.95, has a mass flow rate of 11.2 kg/s, and has a surface temperature of 50°C
By calculating the entropy generation for each turbine, determine which option has a lower degree of irreversibility.
We need at least 10 more requests to produce the solution.
