I don't need to trust you. A larger pipe will has less frictional flow losses than a smaller pipe providing the friction coefficient is close to the same.. IE smooth pvc pipe for both pipes.. The Velocity of the water is less in a larger pipe at the same flow rate, so you have less friction in the pipe. Your table that you should is to help calculation friction using just length of pipe rather than adding in the actual fittings that you are using. The velocity is what makes the larges effect in friction.

Here is how you calculate the friction of a fluid in a pipe.

Trust you your an engineer, so why do you say you are an engineer and a student at the same time? Me I already have an engineering degree.
