Sandlercorrespondingstates

Corresponding states utilities from Sandler's 5th ed.

Sandlercorrespondingstates implements a python interface to a corresponding states calculations using charts from Chemical, Biochemical, and Engineering Thermodynamics (5th edition) by Stan Sandler (Wiley, USA). It should be used for educational purposes only.

Installation

Sandlercorrespondingstates is available via pip:

pip install sandlercorrespondingstates

Usage

Command-line

$ sandlercorrespondingstates state -n methane -P 7.5 -T 400 
T  =  400.00 K
P  =  7.50 mpa
Tc =  190.40 K
Pc =  4.60 mpa
Tr =  2.10
Pr =  1.63
v  =  0.000435 m3/mol
Z  =  0.98
Hdep = -438.15 J/mol = -0.55 cal/mol-K
Sdep = -1.13 J/mol-K = -0.27 cal/mol-K

>>> Rpv = GasConstant("bar", "m3")
>>> result = cs.dimensionalized_lookup(T=400, P=0.5, Tc=component.Tc, Pc=component.Pc/10, R_pv=Rpv)
>>> print(result.report())
