Purchased Costs for Compressors and Drives (Cost Data for Compressors and Drives Taken from R-Books Software by Richardson Engineering Services, Inc. Equipment Cost Data to Be Used with Equation (A.1)įigure A.1. This form of the graph clearly illustrates the decreasing cost per unit of capacity as the size of the equipment increases. It should be noted that in these figures, the data are plotted as Cop/A as a function of size attribute A.
These data are also presented in the form of graphs in Figures A.1–A.17. The data for K1, K2, and K3, along with the maximum and minimum values used in the correlation, are given in Table A.1. Data for the purchased cost of the equipment, at ambient operating pressure and using carbon steel construction, Cop, were fitted to the following equation: where A is the capacity or size parameter for the equipment. The bare module factors for these units are taken to be the field installation factors given by Guthrie. In general, these units are generally bought as a package, and installation in the plant is not expensive. For this new equipment, bare module factors were not available, nor were pressure factors or materials of construction factors.
