The thermal expansion below the Néel temperature shows large contributions of magnetic origin to the volume. The spontaneous volume magnetostriction is negative and amounts to −1.1 × 10−3 for GdCu2. At the
As a result, the annular liquid will also increase. The liquid volume tends to expand and its compressibility is low, which is different from gas. However, the expansion of annular liquid is restricted by trapped annulus because expanded liquid exceeds the capacity of tapped annulus (Zhang et ...
It might not be possible to increase the tubing diameter if the well produces some amount of liquids because the lower gas velocities might make the well load up with liquids; in this case, the liquid is usually removed with the use of metallic plungers as explained in chapter: Gas Lift ...
Based on the two theoretical model, the calculated minimum thermal conductivity of magnesite from 0 to 80 GPa is shown in Fig. 13. It is seen that the minimum thermal conductivity of magnesite increases with the increase of the external pressure, the calculated results using the Cahill’s ...
Based on the results of HP-XRD studies, one would suggest that pressure-induced superconductivity is connected to the observed orthorhombic phase appeared at high pressure. If this were the case, one would expect the diamagnetic signal after 30 GPa would substantially increase as the material bec...
Why is thermal expansion an important consideration for engineering? Why is it that an aneroid barometer is able to measure altitude as well as atmospheric pressure? Why does the air pressure in a car tire increase during driving? Explain in words using physics...
It is worth observing, however, that the increase in the number of dips causes them to be spectrally closer, which can reduce the dynamic range of measurements. Additionally, increasing the sensor’s length can limit its applicability. To determine the dynamic range of the embedded-core fibre ...
Thermal expansion of gas during a fire will result in increased pressure if the fire takes place in a relatively closed compartment [1]. The phenomenon has received only little attention in the history of fire science because most studies have been performed in enclosures with large opening to ...
Isosymmetric pressure-induced bonding increase changes compression behavior of clinopyroxenes across jadeite-aegirine solid solution in subduction zones. J. Geophys. Res.: Solid Earth 122, 142-157. [80] Xu, J.G., Zhang, D.Z., Fan, D.W., Zhang, J.S., Zhou, W.G., 2018. Phase ...
Increasing charge can only increase pressure-boosting amplitude due to inner combustion. Not only can the action time not be prolonged, but it may be shortened because the increase of pressure may increase the combustion rate. 2. The pressure-boosting process required is actually difficult to gener...
