In such a case, the bulk modulus remains high, the x-component of the internal force is positive due to the generation of the peak in the chambers and the delivery line is stiff.
The effective acoustic compliance and effective bulk modulus are determined by the following expressions, respectively:

The study of Zimmerman [31] provided a theoretical basis on analyzing the influence of Terzaghi effective stress on the effective rock bulk modulus. Bouteca [32] and Hart (1998) yielded similar conclusions after experimentation.
The identified values of fluid density and bulk modulus of the fluid are summarized in Table 1.

The biodiesel N[O.sub.x] specific increase effect is related to the differences in physico-chemically characteristics (viscosity, density, bulk modulus of compressibility, bond structure, and cetane number), fuel injection timing and spray char acteristics, and engine operation condition, with major influences on the combustion process (Mazzoleni et al.
(ii) Almost every EOS, new or old, can be fitted to a given range of P-V data by adjusting the values of the zero pressure, isothermal bulk modulus ([B.sub.0]), and its pressure derivatives ([B'.sub.0], [B".sub.0]) [2].
For example, density influences the conversion of volume flow rate into mass flow rate [1], whereas the compressibility (the reciprocal of bulk modulus) acts on the fuel injection timing [2,3].
The crystal ionicity is one of the key parameters of semiconducting materials in discussing problems in the field of elastic constants, cohesive energy, heat of formation, bulk modulus and crystal structure.
