Calculation of Residual Enthalpy & Residual Entropy Video Lecture - Civil Engineering (CE)

then this is the video - in the thermo
dynamic of course the part with logic
and this video is about calculation of
residual enthalpy and residual entropy
and then the calculation of copy and
entropy based on ideal gas entities
ideal gas entropy set which is the
compressibility
using general
thermodynamic relations
it is possible
to derive that residual enthalpy over
our T equals minus T times the integral
from 0 to pressure the partial
derivative of x to the M over T we do
this constant temperature this is
equation 646 and a similar equation or
the residual entropy is minus integral
from zero
finest interval from zero to P of minus
1 that is 646 both these equations are
residual entropy residual entropy as a
function of the compressibility and also
the Gibbs free energy the residual of X
is the integral from 0 to 1
so and if we know or tablet set as a
function of pressure and temperature we
can calculate H R this part if we know
set as a function of pressure and
temperature then we calculate residual
enthalpy and residual entropy
in video 1 it was shown
how to calculate ideal gas the enthalpy
IQ gas entropy from CP correlations
from
the definitions of HR the enthalpy is
then the Presidium enthalpy plus the
ideal gas enthalpy the entropy is the
son of the procedure entropy plus their
ideal gas entropy and Gibbs free energy
it is also that residuals Gibbs free
energy plus the ideal gas this free
energy so then if we know set as a
fashion opt if we know CP correlations
then we can calculate the enthalpy and
entropy and Gibbs free energy the
challenge
for tightening sit is soul
by solving equation for States
and this will be shown in
video 3 so this is the end
