Web3. Size all of the equipment with the precision required to obtain the parameters needed for manufacturers’ cost quotations or to estimate costs from charts. 4. Analyze the process carefully to determine what “plant cost factors” should be used, and then prepare a detailed breakdown of the total plant cost package. WebAn analysis of the cost of individual pieces of equipment shows that the size factor’s exponent will vary from 0.3 to unity, but the average is very near to 0.6, thus the name for the rule of thumb.
