QUESTION 8 An adiabatic turbine expands steam from 500°C and 3.5 MPa to 200°C and 0.3...
Please show steps. Steam at 0.3 kg/s enters an adiabatic turbine at 2 MPa and 500°C. It exits at 100 kPa. If the isentropic efficiency is 95%, how much power is produced, in units of kW? Correct Answer is 514.1 m/s Thank you.
2. STEAM enters a reversible, adiabatic turbine at 6.0 MPa and 500 C. It leaves at 10 kPa. The mass flow rate is 40 kg/s. What is the power output of the turbine in kW? (Hints: W_dot = m_dot (h_2-h _1) and s_1=s_2). a) 1243 kW b) 2663 kW c) 33,570 kW d) 41,000 kW e) 49.725 kW
In a reheat-cycle power plant, steam enters the high-pressure turbine at 5 MPa, 450°C, and expands to 0.5 MPa, after which it is reheated to 450°C. The steam is then expanded through the low-pressure turbine to 7.5 kPa. Liquid water (Vi 0.001 m/kg) leaves the condensor at 30°C, is pumped to 5 MPa, and returned to the steam generator. Each turbine is adiabatic, with an isentropic efficiency of 81.6 % and the pump efficiency is 848 %. If the total...
Steam enters an adiabatic turbine steadily at 7 MPa, 500 °C, and 45 m/s, and leaves at 100 kPa and 75 m/s. If the power output of the turbine is 5 MW and the isentropic efficiency is 77 percent, determine: A. the mass flow rate of steam through the turbine, B. the temperature at the turbine exit, and C. the rate of entropy generation during this process.
Steam enters an adiabatic turbine steadily at 3 MPa and 450°C at a rate of 8 kg/s and exits at 0.2 MPa and 150*C. If the surrounding air is at 25°C and 100 kPa, determine: a. The specific flow exergy of steam at turbine entrance b. The specific flow exergy of steam at turbine exit c. The rate of flow exergy change in the process.
