Sharp convergence rates for darcy's law

WebbRemember that a number raised to the zero power is equal to 1, thus [CO] 0 = 1, which is why the CO concentration term may be omitted from the rate law: the rate of reaction is solely dependent on the concentration of NO 2.A later chapter section on reaction mechanisms will explain how a reactant’s concentration can have no effect on a reaction … Webb1 maj 2006 · Fig. 2 depicts the discontinuous velocity–pressure elements studied. Dots correspond to the velocity nodes and circles correspond to the pressure nodes. However, we observe that for all cases in which k ⩾ 1 and l ⩾ 1, convergence was obtained and observed to be at approximately optimal rates in the sense that the L 2 —rate of velocity …

Webb6 feb. 2015 · With country fixed effects, the estimated convergence rate is misleadingly high. With data starting in 1870, country fixed effects are reasonable and the estimated convergence rate is 2.6%. Combining the two estimates suggests conditional convergence close to the ‘iron-law’ rate of 2%.
