Question

Find the second law efficiency of the steam turbine operating steadily at initial pressure of 3 MPa and initial temperature of 4500C . The final conditions of steam at 0.2 MPa and 2000C . Neglect the kinetic and potential energy changes. The heat loss from the steam turbine to the surroundings is 250 kW. Assume the mass flow rate of steam is 7 kg/s

Answer 1

Explanation:

The cost of energy and fuel is rising. Emission limits are becoming stricter. And the pace of change is accelerating across markets and industries. Amidst these challenges, a single strategy has emerged as the best path to sustainability, increased competitiveness in highly contested markets, and combatting climate change – efficiency optimization
