Yes, there is a 'standard' pressure. It is equal to one atmosphere which is 14.7 pounds per square inch [or 760 mm of Hg barometric pressure]. I really doubt that the evaporation rate of a puddle on the floor as you describe would be significantly affected by changes in local atmospheric pressure. Local relative humidity would probably have a greater effect -- high humidity leading to slower evaporation.... Ken
