This book was released on 1971 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transport property measurements with ultrasonic techniques are discussed over the entire temperature (100-15,000 degrees) and pressure (1-1000 atm) ranges. A chart of various techniques for the determination of transport properties in the various temperature and pressure ranges is given. Sound absorption and sound speed determinations were used to obtain thermophysical properties of argon, helium, nitrogen and air at room temperature and pressures between 1-500 atm. Several variations of pulsed ultrasonic techniques were used to obtain maximum precision in the gas property measurements. Sound speeds accurate to approximately 0.1% were obtained in all the gases. Thermal conductivity and specific heat ratios were deduced for air. A cavity technique was developed for high accuracy (
