    This document calculates the pressure drop in a 125mm diameter pipe that is 45m long, carrying a liquid with a density of 1000kg/m3 and viscosity of 1cP at a flow rate of 80m3/hr. It determines the velocity in the pipe is 1.81m/s, the Reynolds number is 226468.51, and the friction factor is 0.0025, resulting in a pressure drop across the pipe of 16346.51N/m2 or 124.23mmHg. It also accounts for additional 17.25m length from miscellaneous losses from components like bends and valves.
