Determine work output unit mass of air & thermal efficiency, Physics

Assignment Help:

Consider air (ideal gas) as working substance inside a piston-cylinder device (closed system). This air undergoes a power cycle as shown in figure. Determine work output per unit mass of air and thermal efficiency. Analyze each and every process of the cycle. Use cold air standard analysis with Cp and Cv as constants. For air, Cp=1.007kJ/(kg K) and R=0.287 kJ/(kg K).  

P3=1 MPa, P2=0.42 MPa, P1=0.1 MPa

v2=v3= 1.1 m3/kg

v1=v4
