Influence of Viscosity Variation on Coefficient of Friction in Pipe Flow with Different Pipe Materials and Flow Rates using Taguchi Design Method

The friction and friction factors are critical factors in flow through pipes, and heat ex-changer etc. The minimal friction is not only beneficial for pumping cost perspective, but also it reduces the loss of energy. All experimental tests were performed in accordance to Taguchi L9 orthogonal array on cast iron, aluminum, and copper pipes to study the effect of variations of viscosity, flow rates, and pipe materials on the friction factor.
