An equimolar mixture of argon and air is to be used as the working fluid in a closed-loop gas-turbine cycle. The mixture enters the turbine at 3 MPa and 1400 K and expands isentropically to a pressure of 200 kPa. Determine the work output of the turbine per unit mass of the mixture. З MPа 1400 K Ar - Air Turbine 200 kPa Select one: A. 900 kJ/kg B. 450 kJ/kg C.603 kJ/kg D. 867 kJ/kg E. 720 kJ/kg

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...

We put a mixture of helium, oxygen and nitrogen gases in a closed container at 25 ° C. Container pressure in this case is 300 kPa. By a process, we remove all helium gas in the mixture from the closed container. Container pressure in this case reaches 250 kPa. What percentage of the gas mixture did the initial mixture of helium molecules contain? If there are 14 grams of nitrogen and 32 grams of oxygen in this container, what is...

Problem 2/2 (50%) -The gas-turbine cycle of a combined gas-steam power plant has a pressure ratio of 12. Air enters the compressor at 310 K and the turbine at 1400 K. The combustion gases leaving the gas turbine are used to heat the steam at 12.5 MPa to 500 C in a heat exchanger. The combustion gases leave the heat exchanger at 247"C. Steam expands in a high pressure turbine to a pressure of 2.5 MPa and is reheated in...
