It would pro all the values from App. A.2. single equation to that set of data. If one considers only the values for 2.5 inch n diameter and larger, then t = 0.1366 in + 0.02 R 2 = 0.994. Thus, for these pipes, A ≈ 0.1366 inch and B However if one fits the sizes from 1/8 to 2 in nominal, one finds t = 0.0676 in + 0.0550 D in R 2 = 0.803. fitting a quadratic to this data set, showing that th respond very well to the linear model....
