A Redlich-Kwong type of equation of state for gaseous CO2 with a and b being functions of molecular volume is proposed. This equation fits observed P-V-T data for gaseous CO2 from -50o to 1000oC and from 1 bar to 10 kbar, and predicts observed heat capacity values quite well. Geoche...
In marked contrast to the glacial era, BIT-index and MST values are inversely correlated during the Holocene (11.7 kyr to present, or broadly encompassing MIS1:ρ = −0.79,P < 0.001,n = 62; Fig.5a), meaning that in the current interglacial climate mode, higher tempera...
The inlet temperatures were averaged to give an air inlet reference temperature; their variation was small, generally within 0.5°C. The readings of the five outlet sensors were also averaged. They were used to determine the reference temperature difference in the heat output calculations. View chap...
Therefore, temperature dependency measurements require the same set-up as for STC measurements and in addition the possibility to heat up and cool down the DUT. Typically, temperature chambers are used. The offered temperature range is at least 25–65°C; modern temperature chambers even offer ...
{\ddagger }S\). Note that for a heat capacity change of activation equal to zero,\({\Delta }^{\ddagger }{C}_{p}=0\),MMRT predicts an exponential temperature dependence of the CO2production rate that is equivalent to that of the Arrhenius equation. Physically plausible deviations from ...
It becomes apparent that the radiative heat transfer is in the same order as the total convective heat transfer. A generalized equation is developed to correlate the temperature rise and total loss for pot-core components of the same height. In addition, through an experimental example, we show...
The next frontier in heat pumping is to extend the economic operating envelope to supply the 100–200 °C range, where an estimated 27% of industrial process heat demand is required. Most high-temperature heat pump cycles operate at pressures below the refrigerant's critical point. However, ...
Tm is the temperature at which half the primer strands are bound to the target. It depends on base composition and can be roughly estimated as Tm=4G+C+2A+T However, this equation neglects the dependence of Tm on strand concentration, salt concentration, and base sequence. Typical errors for...
The strength of materials depends on the rate at which they are tested, as defects, for example dislocations, that move in response to applied strains have intrinsic kinetic limitations1,2,3,4. As the deformation strain rate increases, more strengthening mechanisms become active and increase the ...
In the geothermal development of hot dry rock (HDR), both the drilling of the wellbore and the heat exchange of the heat reservoir involve the effects of different cold and hot conditions on the high-temperature rock mass. The testing machine for rock mechanics was used to conduct a uniaxial...
