Material Properties

Construction in civil engineering demands high strength, durability, and longevity. These targets can be achieved by better design and analysis, along with the correct choice of materials. Different materials have different properties and hence, they respond and performs differently under the various condition of external loadings. It is therefore a critical task of an engineer to select the right material based on the property that the material is supposed to function in real-time. When speaking about the property, there are different categories of material properties like chemical property, physical property, mechanical property, electrical property, magnetic property, thermal property, etc. These material properties form the basis of material selection in various applications.

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?
