How much work potential is wasted in power plant that takes in steam at 5 kPa + delivers saturated liquid at the same pressure? condensor of a quality of 0.85 and a

A steady stream of steam passes through an adiabatic turbine. It enters at 10 MPa, 450 °C and 80 m/s and at the exit it is 500 KPa, 40% quality and 30 m/s. The mass flow of the steam is 12 kg/s. a) With the power that comes out of the system, 252 100 W bulbs can be lit. Calculate the efficiency of the system. b) What is the area of ​​the duct at the entrance? c) What is the volumetric flow at the outlet? d) What is the temperature of the steam at the outlet?

3. An adiabatic compressor takes argon from 100 kPa, 300 K to 2000 kPa. The compressor efficiency is 80%. (a) Find the outlet temperature (K) and the work (kJ/kg) (b) Find the entropy generation (kJ/kg-K)

A- An adiabatic steam turbine has an inlet of 2 kg/s water at 100 bar, 400 °C with velocity of 15 m/s. The exit is dry saturated at 100 kPa and very low velocity. Find the power produced.
