Wet steam flowing at 4kg/s with a volumetric flow rate of 0.04m^3/s is initially at 80 bar.
a) This stream is isovolumetrically cooled and decompressed to 40 bar. What is the total enthalpy change for this process in kW?
b) This stream is throttled through a valve to 20 bar. What is the total entropy change for this process in kW/K?
c) Finally, 7.63 MW of heat is added to the stream isobarically. What is the temperature change for this process?
d) What is the total change in Gibbs Free Energy for this entire process?
