Web(Drag area is 2.44 m 2) Assume all values are accurate to three significant digits. By what factor does the drag force on a car increase as it goes from 65 to 110 km/h? Calculate … WebRemember this is normalized, so for a bigger D at the same Re you should get the same Cd. The reason drag decreases for bluff bodies with increasing Re has everything to do with the size of the wake region. The thing is the separation point is Re dependant. In the fully turbulent regime, the flow stay attached longer so smaller wake and lower Cd. groitl plattling
