Enter the maximum shockwave pressure (Pa), the density of the medium (kg/m^3), and the velocity of the object (m/s) into the Shockwave Intensity Calculator. The calculator will evaluate the Shockwave Intensity. 

Shockwave Intensity Formula

The following formula is used to calculate the Shockwave Intensity. 

SI = P^2/(2*p*v)


  • SI is the Shockwave Intensity (W/m^2)
  • P is the maximum shockwave pressure (Pa) 
  • p is the density of the medium (kg/m^3) 
  • v is the velocity of the object (m/s) 

How to Calculate Shockwave Intensity?

The following steps outline how to calculate the Shockwave Intensity.

  1. First, determine the maximum shockwave pressure (Pa).
  2. Next, determine the density of the medium (kg/m^3). 
  3. Next, determine the velocity of the object (m/s). 
  4. Next, gather the formula from above = SI = P^2/(2*p*v).
  5. Finally, calculate the Shockwave Intensity.
  6. After inserting the variables and calculating the result, check your answer with the calculator above. 

Example Problem:

Use the following variables as an example problem to test your knowledge.

maximum shockwave pressure (Pa) = 1400

density of the medium (kg/m^3) = 1000

velocity of the object (m/s) = 5000

SI = P^2/(2*p*v) =  ?
