Enter the mass (kg), the velocity (m/s), length (m), and the area (m^2) into the calculator to determine the Muzzle Pressure.
Muzzle Pressure Formula
The following formula is used to calculate the Muzzle Pressure.
Pmuzzle = m*V^2 / (2*A*L)
- Where Pmuzzle is the Muzzle Pressure (Pa)
- m is the mass (kg)
- V is the velocity (m/s)
- A is the area (m^2)
- L is the length (m)
How to Calculate Muzzle Pressure?
The following example problems outline how to calculate the Muzzle Pressure.
Example Problem #1
- First, determine the mass (kg). In this example, the mass (kg) is given as .000154 .
- Next, determine the velocity (m/s). For this problem, the velocity (m/s) is given as 1500 .
- Next, determine the area (m^2). In this case, the area (m^2) is found to be .25.
- Next, determine the length. In this case, this is .5m.
- Finally, calculate the Muzzle Pressure using the formula above:
Pmuzzle = m*V^2 / (2*A*L)
Inserting the values from above and solving yields:
Pmuzzle = .000154*1500^2 / (2*.25*.5) = 1386 (Pa)
Example Problem #2
Using the same method as above, determine the variables required by the equation. For this example problem, these are provided as:
mass (kg) = .00006
velocity (m/s) = 2000
area (m^2) = .15
length (m) = .6
Enter these given values yields:
Pmuzzle = .00006*2000^2 / (2*.15*.6) = 1333.33 (Pa)
