Muzzle Pressure Calculator

Formula

To calculate the muzzle pressure (\(P_{muzzle}\)):

\[ P_{muzzle} = \frac{m \times V^2}{2 \times A \times L} \]

Where:

\(P_{muzzle}\) is the muzzle pressure (Pa)
\(m\) is the mass (kg)
\(V\) is the velocity (m/s)
\(A\) is the area (m²)
\(L\) is the length (m)

What is Muzzle Pressure?

Muzzle pressure refers to the pressure exerted at the muzzle of a firearm when a projectile is fired. It is a critical factor in ballistics and affects the performance and behavior of the projectile.

Example Calculation 1

Let's assume the following values:

Mass (\(m\)) = 0.02 kg
Velocity (\(V\)) = 800 m/s
Area (\(A\)) = 0.0001 m²
Length (\(L\)) = 0.5 m

Using the formula:

\[ P_{muzzle} = \frac{0.02 \times 800^2}{2 \times 0.0001 \times 0.5} = 128,000,000.00 \text{ Pa} \]

The muzzle pressure is 128,000,000.00 Pa.

Example Calculation 2

Let's assume the following values:

Mass (\(m\)) = 0.05 kg
Velocity (\(V\)) = 600 m/s
Area (\(A\)) = 0.0002 m²
Length (\(L\)) = 0.7 m

Using the formula:

\[ P_{muzzle} = \frac{0.05 \times 600^2}{2 \times 0.0002 \times 0.7} = 91,428,571.43 \text{ Pa} \]

The muzzle pressure is approximately 91,428,571.43 Pa.
