How to Use the Calculator
- Enter the engine power of your vehicle in horsepower (HP).
- Input the weight of your vehicle in kilograms (kg).
- Provide the drag coefficient (Cd) of your vehicle. This value typically ranges from 0.3 to 0.5 for most cars.
- Enter the frontal area (A) of your vehicle in square meters (m²). This can usually be found in your vehicle's technical specifications.
- Click the "Calculate" button to compute the theoretical maximum velocity.
- The results will be displayed in meters per second (m/s) and kilometers per hour (km/h).
Understanding the Formula
The calculator uses the following formula to estimate the maximum velocity:
V_max = sqrt( (2 * P) / (m * Cd * A) )
Where:
- V_max is the maximum velocity in meters per second (m/s).
- P is the engine power in watts (W), converted from horsepower (HP) by multiplying by 745.7.
- m is the vehicle weight in kilograms (kg).
- Cd is the drag coefficient, a dimensionless quantity that depends on the vehicle's shape.
- A is the frontal area in square meters (m²).
This calculation provides an estimate of the maximum velocity a vehicle could theoretically achieve under ideal conditions. Actual performance may vary due to factors such as aerodynamic efficiency, tire grip, and other real-world conditions.
