A scaled model of an automobile vehicle of width 2.44 m and frontalarea 7.8 sq. m was tested in a wind tunnelto find the aerodynamic dragthat would act on the vehicde when it plies at 100 km/h and to find the power required to overcome this drag. The scale of the model was 16:1. The test revealed that the drag coefficient on the model was 0.46, and it becomes independent of Reynolds numbers greater than 105. Estimate the drag force and the power required for the actual vehicle if the test- section airflow conditions were identical to sea levelatmospheric conditions.
