The mass transfer coefficient, which is related to the flow characteristics within pipe elements, is one of the important parameters to predict the pipe-wall thinning due to flow-accelerated corrosion. In this study, we evaluate the measurement uncertainty of the calcium sulfate dissolution method, which is a method for measuring mass transfer coefficients, to clarify the mass transfer characteristics of pipe elements such as elbows and T-shaped pipes. The relationship between the flow and mass transfer characteristics is also considered based on the results of mass transfer experiments on various piping elements.
