Derived Values - Surface Integral, adding an equation

Please login with a confirmed email address before reporting spam

Hello,

I need to calculate the acoustic radiation force on a particle within an acoustic field. I need to use the time-averaged acoustic pressure field as well as the time-averaged velocity and the equation consists of 2 integrals. Since I need the pressure and velocity fields the calculation should be done in the derived values sections. However, I am uncertain how to incorporate the equation within the surface integral. The equation is shown in the image. Thanks!
