In the friction factor, regarding the equation that depends on the type of flow, laminar or turbulent, if you want to see one of the sources, what is this equation, and depending on the type of flow you have, it is better. You need to know that the fluid you have is the viscosity and dodecane value of this fluid 1.374x10^-3 bass Its density is 749 kg/m3 The roughness of the pipe is its value M 0.0001The acceleration of free fall is g9.81m What would be the effect of adding a fourth pipe in parallel to one of the existing pipes?
