Abstract

Part I: An apparatus was designed and constructed to determine the volumetric behavior of a number of corrosive fluids at pressures up to 10,000 pounds per square inch and temperatures ranging from -30° to 360°F. Photographic illustrations of the equipment are included and the operation and calibration procedures discussed. Some measurements of the volumetric behavior of nitrogen dioxide are presented in graphical and tabular form.

Part II: The isobaric heat capacity at bubble point of 1-butene and 1-pentene was determined at temperatures from 90 to 200°F. These measurements were carried out in the two-phase region in a constant-volume adiabatic calorimeter. The isobaric heat capacity at bubble point was calculated from the directly measured isochoric values by the use of supplementary volumetric data. The latter data were obtained experimentally for 1-butene and were estimated from the law of corresponding states for 1-pentene. The results are presented in graphical and tabular form.

Part III: Values of the eddy diffusivity were determined for turbulently flowing coaxial streams of natural gas and air. The primary measurements included the composition and velocity as a function of radial position and distance from the point at which mixing of the coaxial streams began. The investigations were carried out at gross velocities of 25, 50, and 100 feet per second in a working section 4 inches in diameter and 8 feet in length. The air and natural gas entered the working section at substantially the same relative gross velocities in the case of each set of measurements. Experimental results and derived values of the eddy diffusivity are presented and a method of predicting the composition pattern is discussed.
