The speed of sound of n-heptane, n-octane and their binary mixtures at temperatures T=293.15 to 523.15 K and pressures up to 60 MPa
Annotation
Speeds of sound in liquid n-heptane, n-octane and their binary mixtures were measured at the temperatures T=293.15 to 523.15 K and pressures up to 60 MPa. The pulse-echo method with a frequency of 8MHz and uncertainty of ±0.08% was used. The measured values were fitted by polinomials, as functions of temperature and pressure, and the reliability of the present results was proved by comparison with the literature data.
