Velocity of Sound in Liquid Propane

Experimental determination of sound velocity in liquefied propane-butane gas mixture (LPG)

In this article, experimentally determined values of sound velocity in LPG in a temperature range (–23...+55) °C are presented. The measurements were taken using two industrial LPG samples in a standard five liter pressurized gas tank. The propagation time of a ultrasonic signal with the frequency of 0.7 MHz was measured. To increase the accuracy of measurement, a pulse-phase method was applied...

Radiolysis of Liquid Propane: non-Radical Reactions

The yields of ionic and excited molecule reactions in y-radiolysis of liquid propane from 35 to -130C have been assessed by isotopic analysis of C3Hs-l-C3Ds+Oz and CH3CD2CH3 -1-02 mixtures. From a comparison with gas phase data the following conclusions are reached for the gas to liquid phase change: (a) the ionic decomposition yield rlecreases by :5 69 %, (b) the net excited molecule decomposi...

Influence of Aging Temperature on Mechanical Properties and Sound Velocity in Maraging Steel M350

In the present work, the influence of aging temperature on mechanical properties and sound velocity of Maraging steel M350 was investigated. For this purpose, first, samples were solution annealed at 825◦C for 2 hours and then age hardened at 510◦C-600◦C for 3 hours. Hardness, tensile and impact tests were used for determining mechanical properties and longitudinal ultrasonic velocity was used ...

Radiolysis of Liquid Propane: Radical Reactions

The radical reactions in the liquid phase y-radiolysis of propane have been studied from -130 to 35°C and compared with the gas-phase radiolysis at 35°C. Oxygen was used as a scavenger 10 separate thermal radical yields, and effects· of phase and temperature on the radical yields were assessed. The gas-liquid phase change (a) decreases total decomposition by about 14 %, (b) increMCs disproporti...
