“…This condition is detected with an oscilloscope by maximizing the resulting reinforced waveshape as seen by the receiving crystal. This technique, developed by Greenspan and Tschiegg [1]; has been used on hydrogen [2], oxygen [3], fluorine [4], methane [5], and ethane [6] in this laboratory and the apparatus is described in detail in the earlier publications. Uncertainty in the measured sound velocities is estimated to be 0.05 percent Temperatures were measured using a platinum resistance thermometer calibrated by the National Bureau of Standards on the IPTS 1968.…”

“…Noury [14] measured the speed of sound in the critical region of ethane. Speeds of sound in saturated liquid ethane were measured by Poole and Aziz [15], Vangeel [16], and Tsumura and Straty [2]. Only the data set of Tsumura and Straty [2] covers a large part of the liquid region.…”

“…For ethane, the most accurate fundamental equation of state was published by Bücker and Wagner [1]. For the optimization of the equation of state in the liquid phase, only one comprehensive speed-of-sound data set by Tsumura and Straty [2] was available. These data were measured with a sing-around pulse-echo technique, have an uncertainty of 0.05 % and cover the low temperature range between 100 K and 323 K with pressures up to 37 MPa.…”

Comprehensive and accurate measurements of the speed of sound in pure ethane have been carried out in the liquid and supercritical regions by a double-path-length pulse-echo technique. The measured data cover the temperature range from 240 K to 420 K with pressures up to 100 MPa. The expanded measurement uncertainties at the 95 % confidence level amount to 2.1 mK for temperature, 0.007 % for pressure, and 0.01 % for speed of sound with the exception of a few state points in the vicinity of the critical point, where the uncertainty increases up to 0.016 %. The quality of the measurements is demonstrated by comparisons with literature data and the fundamental equation of state for ethane
