Change of the distilled water layer thickness in time under the evaporation from stainless steel surface was studied experimentally. To register a change in the liquid layer thickness an experimental technique with the use of high-precision confocal method was developed. Change of the thickness of thin layers (less than 3 mm) in time is found to have a linear nature. At decreasing the thickness up to 0.5 mm, linear nature changes to the polynomial. It can be explained by the change in surface tension.
