Thermal Conductivity and Speed of Sound Measurements of Liquid Hydrazine (N2H4) at 293.15K and 0.101 MPa to 2.068 MPa

Abstract

The thermal conductivity of liquid hydrazine was measured by the steady-state hot-wire method at 293.15K and 0.101 MPa. Eight pure organic liquids were used as reference liquids to calibrate the experimental apparatus. The current measurement is in agreement with one recent measurement. However, the current measurement disagrees with the most recent measurement, as well as several previous measurements and estimation methods. The thermal conductivity was determined to change very little over the pressure range of 0.101-2.068 MPa. The current observed pressure dependence is in agreement with one previous pressure dependence measurement. The speed of sound in liquid hydrazine was measured to be 2092 +or- 12 m s-1, in agreement with previous measurements. There are large inaccuracies obtained when estimating the thermal conductivity of hydrazine by using standard estimation methods that utilize speed of sound data.
