... Moving to another question will save this response. Question 7 Compressed air with a flowrate of 8 kg/min flows through a two-stage turbine and heat exchanger system as follows: • At the entrance to the system (point 1), the pressure of the air is 8 bar and the temperature of the air is 359 K. • From 1-2 the air passes through a heat exchanger which increases its temperature to 922 K. • From 2-3 the air passes through a turbine, with a pressure ratio of 3 (i.e. P₂/p₂=3). This first turbine has an isentropic efficiency of 65%. • From 3-4 the air passes through a second heat exchanger, which increases its temperature back up to 922 K. • From 4-5 the air passes through a second turbine with a pressure ratio of 3 and an isentropic efficiency of 80%. The properties of air are: cp = 1.005 kJ/kgk, cv = 0.718 kJ/kgK, R = 0.287 kJ/kgK, and y= 1.4. Select the correct value for each of the following values: ₂) a.
