CHE200 - Chemical Eng Fundamentals
Chapter 5 Single-phase system
Before you carry out a complete material balance on a process, you
usually must determine various physical properties of the process material
and use these properties to derive additional relations among the system
variables.
The following methods can be used to determine a physical property of a
process material:
1. Look it up
- Perry’s Chemical Engineers’ Handbook
- CRC Handbook of Chemistry and Physics
- TRC Databases in Chemistry and Engineering
- Physical and Thermodynamic Properties of Pure Chemicals:

2. Estimate it
3. Measure it
Liquid and solid densities
p=m/V
- When you heat a liquid or a so lid it normally expands. Thus, its
density decreases. In most process applications, however, it can be
assumed with little error that solid and liquid densities are
independent of temperature.
- Similarly, changes in pressure do not cause significant changes in
liquid or solid densities; these substances are therefore termed
incompressible.
