Hi guys

firstly if my vehicle has a drag coefficient of 0.29 a frontal area of 2.43m, and is travelling at 22.3m/s, taking density of air at 1.2kg/m3 is my aero drag 211.115N correct

Secondly the important bit i need to convert this newton value into kwh how can i do this does it need to be multiplied by a time or something.

Thanks for any help.
