Density and Heat Capacity of Liquids from Speed of Sound

Table 6

The average step-size and number of steps taken in the subcritical domain.

Substance	Average step-size, MPa		Number of steps taken
	IBVP-1	IBVP-2	IBVP-1	IBVP-2
Ar	0.073	0.01	37	270
N2	0.056	0.01	36	200
CO2	0.114	0.01	44	500
CH4	0.065	0.001	51	3300

Calculated as ()/number of steps taken.
Constant step-size is used across the domain.
