Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I would like to calculate total number of particles in one periodic wave-section whose radius varies by h(z)=1+A*sin(2*pi*z/L), where A is the profile amplitude and L is the wavelength of one wave-section.

I thought, I will do by volume integration, say integral over V (volume of one wave-section) and the integrand is the concentration C(z,r,t), where z & r are the axial and radial direction respectively, and I want to integrate w.r. to V, i.e., dV.

Can anybody give idea about this calculation?
