DragCoef_SemiTruck

 

 

Function DragCoef_SemiTruck returns  the drag coefficient for a typical semi-trailer truck without fairing.  Fairings may reduce the drag coefficient by 20%

 

 

Inputs

Re - Reynolds number.  (Any value as the drag coefficient is a constant)

 

Outputs

DragCoef_SemiTruck - drag coefficient [-]
