Three methods of estimating radii of spray droplets are discussed and results of their practical application in the case of explosively produced water spray are reported. Parameters of model radii distributions are fitted using the least squares method. Finally, the data obtained for a number of tests are used for estimating fraction of explosion energy used for pulverization of water in the process of explosive production of water-spray.
