An experimental test loop system was designed, developed, and constructed to study the two-phase flow field. Horizontally oriented inlet and branches piping system, with sharp edge T-junction, at a system pressure of 1 bar was investigated. Measurements of air and water mass flow rates and temperatures in slug flow regime with variable inlet mass fluxes, extraction rates, and qualities are presented. Single-phase loss coefficients were determined, correlated and compared with different proposed correlations. The statistical mean predictive accuracy of the measured pressure difference values are compared with the separated flow model and Riemann and Seeger model in the way of parity plot. Riemann and Seeger model showed better predictions with the present data. It is also concluded that the pressure difference depends on the inlet mass fluxes, inlet qualities and extraction rates, and there is a strong interdependence between the separation phenomena and the pressure distribution.
