Evaporation Rate Calculator app for iPhone and iPad

This evaporation rate calculator uses the evaporation rate equations in Paul Uno’s ACI Materials Journal (July/August 1998) article, Plastic Shrinkage Cracking and Evaporation Formulas, which are based on the popular evaporation rate nomograph from ACI 305R, Weather Concreting. Using this tool, you can quickly calculate the evaporation rate based on the concrete temperature, the air temperature, the ambient relative humidity and the wind velocity. As necessary, recommended cautionary and upper limits are provided alongside the calculated evaporation rate.
