... on a spring, with an equivalent mass equal three times that of the water displaced by the bubble, and air pressure following an ideal gas law corresponding to a spring. With this understanding, one is prepared to deal with the effects of interactions among air guns and with the higher-order terms and other...

... made in obtaining the data given in Table 19-12 and in some of the data in Table 19-7 [ 9 ]. The approximate pressures given in Table 19-13 were calculated from the known volume of the bomb, using the steam tables for P-V-T data for water and the ideal gas law for CO 2 . Pressures of the mixture were...

... to a recently published empirical relationship (Moldrup et al., 2000); the capacity factors fitted indicate equilibrium partitioning of the solute between gas phase and water. A one-dimensional numerical model based on the combination of Fick's Second Law and Raoult's Law was used to predict the volatilization...

Relief was so prominent, even after truncation and burial, that the fold provided an ideal environment for development and accumulation of oil and gas in the numerous shallow Pennsylvanian zones on its irregular surface. Accumulations within the Pennsylvanian...

.... The temperature in each case is the same as the temperature at which the Langmuir isotherms were measured (Table 2). In case 3, the water pressure increases linearly from 1 bar at x = 0 to 45 bar at x = L . Ideal gas law was assumed in all cases, and ρ m and ρ e were determined accordingly with units...
