Volumes

Volume usually is the dimensional quantity that involves the evaluation of any three-dimensional figure enfolded inside a closed space. The SI unit (International System of Units) of volume is m3 and the dimensional unit of volume is [L3]. For estimation of the volume of any figure, various formulae are used. Another application of volume includes the reference in the sound levels, the higher the sound intensity, the louder the sound heard, and hence, the larger the volume. The SI unit of sound volume is decibels (dB).

I was wondering in the hydrodynamics how i can determine Cp in the pressure ressistance (coefficient pressure). so the total ressistance will be Rt= Rf+Rp. Given in Coefficients it will be: Ct=Cf+Cp now they say Cp in % of the friction coefficient (Cf). Ct=(1+k)*Cf with 1+k the formfactor. so the total ressistance will be Ct=Cd*1/2*ρ *v^2*S (wetted area m^2, v= velocity in m/s and ρ= 1025 kg/m3 for salt water) kan you explain me how to calculate the Cd in the total resisstance?
