Example 2.9
The same gas as in the previous example is compressed isothermally from 1 atm
and 70 °F
to 5 atm. Find the point and path
functions. V1 = 386.6 ft3/lbmol
Solution
$
Internal energy change for ideal gas
(ΔU) (Equation 2.32):
|
|
$
Work done by the system, W (Equation 2.33):
|
|
$
Heat added to the system, Q (Equation 2.21)
|
|
$
Entropy change, ΔS (Equation 2.34):
|
|
$
Final volume, V2 (Equation 2.35):
