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.

Steam CERE KJ -Valve Control volume boundary Turbine Initially evacuated tank In case of emergencies, a turbine is connected to an active steam pipe line using a valve. When the valve is opened, steam from the pipe line, which is initially at 550°C and 10 MPa, flows through the turbine into a 0.64 m³ tank, which is initially evacuated. The valve is closed when the pressure inside the tank is 1.6 MPa and the temperature in the tank is 300°C. If the entire process is completed adiabatically, what is the amount of work generated from the turbine?
An air-cooled condenser has an expected U value of 30 based on the air-side area. The m²-k condenser is to transfer 60 kW with an airflow rate of 15 kg/s entering at 35°C. If the condensing temperature is to be 48°C, what is the required air-side area? Recall Cp,air = 1.0- kg-K kJ
Homework: A counterflow heat exchanger is located between a collector and a storage tank. The fluid in the collector side is a water-glycol mixture with cp=3840 J/kg. °C and a flow rate of 1.35 kg/s, whereas the fluid in the tank side is water with a flow rate of 0.95 kg/s. If the UA of the heat exchanger is 5650 W/°C, the hot glycol enters the heat exchanger at 59°C, and the water from the tank at 39°C, a) estimate the heat exchange rate; b) if FRUL is 5.71 W/m².°C and collector area is 16 m², what is the ratio FR/FR?
