T1 = Hours to produce the first unit. b = (Log of the learning rate/Log 2) = Slope of the learning curve. If the learning rate for a given operation is 80%, and the first produced unit took 1.000 hours, the hours needed for the thirteenth unit can be calculated as follows: TN = T1(Nb).
But I have seen two ways of calculate the growth rate: Growth rate = Maximum slope value of the Kinetic curve. $Log_{10}$ transformation of the growth data and then calculate the slope. I think the second one is right if you want to calculate the generation time: generation time = $\frac{ln(2)}{Growth rate}$.
