This paper discusses the nature of flow velocity profiles in nuclear plant feedwater system piping, and the impact of flow profile development on flow measurement. The mechanism for flow velocity profile development is described, and the influence of upstream pipe fittings and the relative roughness of the piping inside diameter on flow development is illustrated. The paper defines fully developed flow profiles and illustrates, using several practical applications, how velocity profiles in nuclear plant feedwater piping are rarely fully developed.
