22 Thermophysical Properties at Critical and Supercritical Conditions Igor Pioro and Sarah Mokry University of Ontario Institute of Technology Canada 1. Introduction Prior to a general discussion on specifics of thermophysical properties at critical and supercritical pressures it is important to define special terms and expressions used at these conditions. For better understanding of these terms and expressions Fig. 1 is shown below. 35.0 Compressed Fluid Supercritical Fluid 32.5 e n i L 30.0 l High Density a Low Density c i (liquid-like) t (gas-like) i 27.5 r c o d 25.0 u e s a P =22.064 MPa P P 22.5 cr M ,
