Any moving object through a fluid experiences a force in the direction opposite to the motion which is due to the pressure difference and shear forces on the surface of the object. If we resolve the resultant force in the direction of flow and normal to flow then there are termed as aerodynamic drag force, aerodynamic lift force respectively. If aerodynamic drag acting on the automobiles or aero planes is less, then it will consume a lesser power resulting in less fuel consumption. In the present proposed study we have look after practical aspect of an model of automobile car, (Maruti Esteem). For practical approach, we have to analyze the available model to see the factors, which may reduce drag force on the surface of the moving body. In the present work drag force is calculated on the body of car model experimentally on the basis of our findings drag force is directly proportional to the angle of wind screen, velocity, surface, and fluid viscosity.

Keywords: Aerodynamic drag force, Aerodynamic lift force.
