The Airgun Calculator serves as a valuable tool for determining the velocity of a pellet fired from an airgun. Its function is based on a formula that calculates the velocity using specific parameters related to the airgun and projectile properties.
Formula of Airgun Calculator
The formula used by the Airgun Calculator to determine velocity (V) is as follows:
Velocity (V) = √(2 * Pressure (P) * Barrel Volume (V) / Projectile Mass (m) * 1.4)
Variables:
- V is the velocity of the pellet in meters per second (m/s).
- P represents the air pressure in the airgun's reservoir in Pascals (Pa).
- V stands for the volume of the barrel in liters (L).
- m denotes the mass of the projectile (pellet) in grams (g).
General Terms Table/Calculator
For user convenience, here is a table of commonly searched terms related to airgun calculations:
| Term | Description |
|---|---|
| FPS | Feet per second, an alternate unit for pellet velocity |
| Joules | Energy measure often used in airgun performance evaluation |
| PSI | Pounds per square inch, a unit of pressure |
| Grain | Weight measure of the projectile in the context of airguns |
| Joule Creep | Phenomenon where airgun velocity increases after the pellet exits |
Example of Airgun Calculator
Let's consider an example using the Calculator to demonstrate its functionality. Assume an airgun with a pressure of 2000 Pa, a barrel volume of 3.5 L, and a projectile mass of 0.45 g.
Given these parameters, the Airgun Calculator computes the velocity of the pellet, resulting in V ≈ 109.42 m/s.
Most Common FAQs
Ensure you input pressure in Pascals (Pa), barrel volume in liters (L), and projectile mass in grams (g).
Velocity impacts accuracy, target penetration, and overall performance, hence it's a critical factor for users to consider.
Yes, the calculator's formula is applicable across various airgun types as long as the inputs match the specific gun's parameters.
