In today's industries, where most of the aircraft, automobiles are designed using different software's and the same time attention is paid on reducing the cost of the system so it becomes very necessarily to examine them with preliminary results. Scientists and engineers used various small models of automobiles and air-crafts so as to study the effect of air which is placed in the test section of sub-sonic or low speed wind tunnel. The wind tunnel design in this case is capable of generating laminar flow. In test section, to analyse the internal flow manual analysis was used. This paper primarily focuses on development and fabrication of low speed wind tunnel, flow visualization of various objects and calculation of drag coefficient of an object. Our design includes convergent section, test section and divergent section. Convergent section frontal area measures 81cm*81cm*61cm, test section area measures 30cm*30cm*61cm and divergent section
