This paper is to discuss the relationship between the jet characteristic and turbulent diffusion coefficient which is a factor of Reynolds stress giving rise to vibration and noise that take place in diffuser and orifice through the theoretical analysis for the flow mechanism by means of momentum and energy theory and experiments of these pipeline components. Therefore, it has been made clear that the turbulent diffusion coefficient can be used to make a quantitative analysis on the level of these datum of pressure loss factor for the diffuser and orifice.
