In present article a theoretical attempt is made to present the variation of attenuation by water droplets in air for various values of particle volume fraction and Prandtl number. It is concluded that as particle volume fraction increases dispersion has a decreasing trend while attenuation increases and attend maximum value and then decreases continuously. Similarly for fixed values of and for different value of Prandtl number dispersion decreases and reached minimum and then increases while attenuation increase and attend the maximum value and then decreases. In preparation of graphs MATLAB is used .
