This paper presents simulation investigation of the velocity contour with in a transonic converging-diverging (CD) nozzle prototype to produce higher pressure and momentum output. Carl de Laval invented two-pieces nozzles, converging and diverging. The discovery of this nozzle greatly facilitates the mass delivery process. A light mass particle is a mass that easily flows with air that can be compressed through the nozzle. It also can be applied in various ways, one of them is vaccination in health. Nozzle is an important part of the gene gun which used to accelerate DNA in particle form with a gas flow to reach adequate momentum to enter the epidermis of human skin and elicit immune response.
