* PLEASE JUST SOLVE PARTS E,F,G,H
The system to be studied in this problem has an average enthalpy of
vaporization of 32kJmol, an average CPL of 146Jmol-C, and an
average CPV of 93Jmol-C. Variable names for the various stream
flow rates and the heat flow rates are given in the diagram. The feed
can be liquid, vapor, or a mixture represented using subscripts to
indicate the vapor and liquid flows, F=FV+FL. The enthalpy flow
due to feed can be represented as: for saturated liquid, FLHsatL; for
saturated vapor, FVHsatV; for subcooled liquid, FLHsatL+FLCPL(TF}
{:TsatL); for superheated vapor, ; and for a
mix of vapor and liquid, FLHsatL+FVHsatV.
a. Use a mass balance to show FV+VS-VR=LS-LR-FL.
[For parts (b)-(f), use the feed section mass and
energy balances to show the desired result.]
b. For saturated vapor feed, FL=0. Show VR=VS+FV,LS=
LR.
c. For saturated liquid feed, FV=0. Show VS=VR,LS=LR+
FL.
d. For subcooled liquid feed, FV=0. Show VR-VS=
FLCPTF-TsatHvap.
e. For superheated vapor feed, FL=0. Show LS-LR=
-FVCPTF-TsatHvap.
f. For a feed mixture of saturated liquid and saturated vapor.
Show VR=VS+FV,LS=LR+FL.
