The going calculation provides an analysis of steady-state vehicle operation. Power and fuel requirements are indicated. Uphill or downhill road grades and head winds or tail winds can be specified.
Enter vehicle weight, drag coefficient, frontal area, tire pressure, brake specific fuel consumption (BSFC), altitude, road grade (positive or negative), head wind or tail wind, and speed. Calculate power to overcome aerodynamic drag, power to overcome rolling resistance, power to overcome gravity, net power required, power to overcome altitude, total power required, weight to power ratio, fuel consumption, and percentage of power lost due to altitude.
