  2. 2071 ShrawanChapter 9: Flow Past Submerged Bodies9.2 Expressions for Drag and Lift

    Automobile having a projected area of 1.6 m² and drag coefficient \(C_d=0.35\) travels at a uniform speed of 60 km/hr in still air of density 1.2 kg/m³. Calculate the power required to overcome the air resistance. If the drag coefficient of the automobile is reduced by 15% by improving streamlining, what percentage increase in speed could be obtained with the same power?
