A graduating engineering student opted to choose a thesis topic which involves the study of fluid flow. In his experimental setup, he used a circular tube in order to analyze the pressure drop (ΔP). During the preparation for the actual experimentation, he found out that the parameters involved were tube length (l), hydraulic diameter (d), surface roughness (e), with fluid of density (ρ) and viscosity (μ) moving with average velocity (v). Due to his insufficient knowledge on fluid mechanics, he approached you and asked for helped as someone who passed the course. In order to prove your knowledge gained, you now need to obtain an expression in non-dimensional form in order to analyze the relationship among the parameters involved.
