Physical Properties

The common assumption that for real liquids cv can be approximated by cp is not correct. To get accurate cv values, use equations of state.

Use these graphs and equations to calculate liquid viscosity at any temperature.

Use these techniques to select, troubleshoot and maintain spray nozzles for optimal results.

Physical property values are essential for many chemical engineering tasks. This article reviews sources of physical property data, discusses the use of experimental methods to measure properties, and details several types of estimation techniques.

Addressing the challenges outlined here will help ensure that engineers of the future have the data they need.
