Enthalpy increment measurements on liquid ethane between the temperatures 146.0 K and 256.2 K, at pressures (≈1.6, 3.20, and 5.07) MPa

Abstract

Isobaric enthalpy increment measurements have been made on liquid ethane. The temperature and pressure ranges covered by the measurements are (146.0 to 256.2) K and (1.16 to 5.07) MPa. The measurements have an average standard uncertainty of ±0.07 kJ·kg −1or 0.21 per cent of the enthalpy increment. A new flow calorimeter test loop that avoids the two-phase region is described. The flow calorimeter used is of the electrically heated type.
