WebApr 9, 2008 · The Birch growth model is equivalent to the logistic equation for c = 1 and to exponential growth for c = 0. The maximum growth rate is rw/(⁠ ⁠) 2 when the plants have the size w/(⁠ ⁠) When c<1, the maximum growth rate occurs at v>w/2; when c>1, the maximum growth rate occurs at v WebThe concept of the 3rd-order Birch-Murnaghan equation of state (BM3-EOS) is almost the same as that of the 2 nd -order Birch-Murnaghan equation of state (BM2-EOS). Difference is that change in Helmholtz free energy, F, is expanded not to the 2 nd -order ( BM2 Eq. 3) but to the 3 rd -order the finite strain f ( BM2 Eq. 2 ): By differentiating Eq.
