231 The isothermal compressibility of a gas may be calculated from an empiric equation expressing the dependence of V upon P at constant temperature.1957Encycl. Brit. VIII. 123/2 Under ordinary conditions the adiabatic constants for a solid substance are practically the same as the corresponding ...
The adiabatic compressibility, variation of specific volume with temperature and the specific heat at constant pressure have been measured for 24 liquids after careful purification. The isothermal compressibility and the ratio of specific heats are obtained in each case by calculation. A comparison is ...
The theory takes account of wall friction, compressibility and flow choking. A set of working formulas is obtained. In the second part, results of experiments on homogeneous bubbly flows of water-air mixtures in a 1-in. Pipe are reported. Criteria for the occurrence of bubbly flow are ...
from the existing literature and used for calculating the isothermal compressibility with the help of the well-known thermodynamical equation. Small variations in these do not appreciably affect the result, and hence the degree of accuracy with which they have been determined is of little consequence...
The Partially Filled Pipe (IL) block models a pipe with the capacity for varying internal liquid levels.
When dynamic compressibility is off, the liquid is assumed to spend negligible time in the pipe volume. Therefore, there is no accumulation of mass in the pipe, and mass inflow equals mass outflow. This is the simplest option. It is appropriate when the liquid mass in the pipe is a negli...
(K); and Z is the gas compressibility factor, which is dimensionless); then, the mole number of the sample adsorbed gas is ni=n1–n2, and the volume of the adsorbed gas at every pressure point is Vi=ni×22.4×1000; the quantity of the adsorbed gas at every pressure point is finally...
For an ideal gas, pressure-volume diagrams are used to determine the properties of the gas at specific points on a thermodynamic cycle, and so they help determine the nature of the processes that build the cycle. Also, P vs V diagrams help determine the wo...
These studies also focus on compressibility effects [18], [19]. Generically, there are many difficulties in finding accurate turbulent models since the details of the experimental data are not well known. In addition, the thermal flow conditions may not be well posed in the geometry (see Ref....
