An ideal gas mixture consists of 35% Argon (Ar) and 65% carbon dioxide (CO2) gases, by mass. The mixture is now expanded isentropically in a turbine from 1200K and 1.2 MPa to a pressure of 150 kPa. For the two components use properties listed in Table A1 and Table A2a (at 300K) – ideal gas with constant specific heats. The mixture temperature at turbine exit is, in Kelvin (round to nearest integer; for example if the answer is 345.6K, write...

1. (10 points) A combined gas turbine-vapor power plant has a net power output of 45 MW. Air enters the compressor of the gas turbine at 100 kPa, 300 K, and is compressed to 1200 kPa. The isentropic efficiency of the compressor is 84%. The condition at the inlet to the turbine is 1200 kPa, 1400 K. Air expands through the turbine, which has an isentropic efficiency of 88%, to a pressure of 100 kPa. The air then passes through...

A combined cycle gas turbine / vapor power plant uses the turbine exhaust as the energy source for the boiler. Each power system uses a single turbine. The gas power system is modeled as an ideal air-standard Brayton cycle. The vapor power system is modeled as an ideal Rankine cycle. Given specific operating conditions determine the temperature and pressure at each state, the rate of heat transfer in the boiler, the power output of each turbine, and the overall efficiency....

7. An industrial turbine process requires a steady 0.5 kg/s of air at 200 kPa. This air is to be the exhaust from a specially designed turbine with inlet state 400 kPa, 400 K. The heat transfer could be obtained from a source at 500 K if necessary. This process may be assumed to be reversible and the changes in kinetic and potential energy are negligible. Air is an ideal gas, with constant specific heats, using Table A.S (a) Which...
