It is widely used in Pressure Diffusion @model and transient data analysis (PTA / RTA ) of strongly compressible fluids.
The name "Pseudo-Pressure" is misnomer as Pseudo-Pressure is not actually a pressure in terms of physical property and has a different dimension.
The value of Normalized PseudoPressurePseudo-Pressure differs from Pseudo-Pressure by a constant multiplier but represents an actually pressure in terms of physical property and has the same dimension.
