Brigham Young University Thermophysical Properties Laboratory

byutpl

byutpl (Brigham Young University Thermophysical Properties Laboratory) is a suite of tools for chemical and other engineers to

1. perform thermodynamic calculations using cubic equations of state and
2. obtain thermophysical properties for a limited set of compunds.

Its target audience is students in chemical and mechanical engineering majors. Before using this tool, students should fully understand the principles behind the calculations being performed.

It is most useful for courses in thermodynamics, fluids, and heat and mass transfer.

Example Commands

The following command returns the residual heat capacity in units of J/mol, calculated using the Soave, Redlich, Kwong equation of state, at 300 K and 500000 Pa for the liquid phase of the compound described by

• critical temperature = 369 K
• critical pressure = 4800000 Pa
• acentric factor = 0.81

srk.hrl(300,5E5,369,48E5,0.81)

The following command returns the liquid viscosity of water at 400 K in units of Pa*s

wtr.lvs(400)
