Evaporation Losses Control in Water Surface by Chemicals

The extremely high rate of Evaporation from water surfaces day by day is reducing the optimal utilization of water reservoirs. The work presented in this study aims to investing the use of Chemical films as Evapo retardars for reduction of evaporation from the open water surface so as to increase the storage efficiency. Particular emphasis will be on practical procedures and techniques that professionals can use to estimate and/or to suppress evaporation from shallow water bodies. The natural evaporation loss taking place from pan evaporimeters of two or more chemicals were observed and compared. The important meteorological factors affecting the natural evaporation such as Temperature, Relative Humidity, Wind Velocity, Sunshine Hours, etc. were also observed. Cetyl and Stearyl Alcohols were selected to reduce the evaporation during the study period in Newasa Phata Ahmednagar region with Class-A evaporation pan
