This is a small sample of my data which covers a period of 2 full years.
These data represent the decreasing speed of the thickness of an object based milimeters per year. Knowing that my object has a base thickness of 5mm, and the thickness loss per day expressed in mm/year, how can i calculate the total thickness loss for a given period of time of say 2 years?
Thank you very much in advance
Take an average of your data points. Multiply by the number of years you wish to estimate. This will give you an approximate mm loss over that many years.
E.g. suppose your average was 0.4mm/year and you want to estimate 3 years of loss.
0.4mm/year * 3years = 1.2mm
