The total heat input to a vehicle, denoted by Qtotal, is the amount of heat energy that is supplied to the vehicle during a given period of time. It is a measure of the total thermal energy that is transferred to the vehicle from its surroundings.
- Total heat input to the vehicle (QTotal) in J
- Skin friction drag coefficient (Cf)
- Total drag coefficient (CD)
- Mass of vehicle (m) in kg
- Velocity of vehicle (VE) in m/s
