Where:
MPH = Speed in miles per hour
FA = Frontal area in square feet
HP = Horsepower
150,000 = A conversion constant
Example:
What is the horsepower required to overcome air resistance of a vehicle
travelling 40 miles per hour and having a frontal area of 80 square feet?
Where:
MPH = Speed in kilometres per hour
FA = Frontal area in square metres
P = Power in Watts
77.86 = A conversion constant
