First, we fix each of the principal states.
State 1: p1 = 0.08 bar = 8 kPa, saturated liquid.
h1 = 173.88 kJ/kg, n1 = 0.0010084 m3/kg
State 2: h2 = h1 + v1 (p2−p1)
= 173.88 + (0.0010084) x(8000 − 8) = 181.94 kJ/kg
State 3: p3 = 80 bar = 8 MPa, T1 = 480oC
h3 = 3348.4 kJ/kg
s3 = 6.6586 kJ/kg−K
State 4: p4 = 0.8 bar = 8 kPa, s4 = s3
h4 = hf + x4 hfg = 173.88 + 0.7944 2403.36 = 2083 kJ/kg
To determine the heat transfer rate
first determine the mass flow rate. The net power output of the cycle is,
