Abstract : The structure of a nomograph for estimating the parameters of exponential decay is described, with its mathematical and graphical bases. An example is given of the type of nomograph and its use is illustrated with a set of sample problems. The suggested structure is compared with that of one previously published by Bourdillon and Lidwell. An alternative useful methodology for parameter estimation involving log log scales on a slide rule is included. (Author)
