Ballistic Coefficient Calculator
A Ballistic Coefficient (BC) Calculator is a tool used to determine the ballistic coefficient of a projectile, which is a measure of its ability to overcome air resistance in flight. The BC is important for predicting a projectile’s trajectory, range, and accuracy.
The calculator typically requires the following inputs:
- Projectile Weight: The mass of the projectile.
- Projectile Diameter: The diameter of the projectile.
- Velocity: The speed of the projectile.
- Drag Coefficient: A value that represents the drag force experienced by the projectile.
Ballistic Coefficient formula
The formula to calculate Ballistic Coefficient (\(B\)) given the projectile mass (\(m\)), drag coefficient (\(C\)), and area (\(A\)) is:
\[ B = \frac{m}{{C \times A}} \]Variable Definitions:
- \( B \) - Ballistic Coefficient (kg/m²)
- \( m \) - Projectile Mass (kg)
- \( C \) - Drag Coefficient
- \( A \) - Projectile Area (m²)
Find the Ballistic Coefficient (\(B\)) for a projectile with a mass (\(m\)) of 0.02 kg, drag coefficient (\(C\)) of 0.3, and area (\(A\)) of 0.001 m².
Answer:
Using the Ballistic Coefficient formula:
\[ B = \frac{0.02}{{0.3 \times 0.001}} \]Therefore, the Ballistic Coefficient is \( \approx 66.67 \, \text{kg/m²} \).
