Entropy generated in an open system.
Superheated water vapor at a pressure of 200 bar and 500°C and a flow rate (mı) = 10 kg/s is to be mixed with
a second stream (m2) of subcooled liquid water at 20°C under steady state conditions. The output (product)
stream (m3) consists of saturated vapor at 100 bar. The mixer operates adiabatically.
Given: [1 bar = 100 kPa)]
P= 200 bar, 500°C :
H= 3238.2 [kJ/kg]
S = 6.14400 [kJ/kg-K]
a) Provide a detailed sketch of the process. Label ALL streams with properties.
b) Find m2 and m3 in [kg/s].
c) What is the entropy generation [kJ/s-K] for the process?
