Multi-holed Orifices (MOs) are widely used in swirling, cavitating and developing flows to reduce pressurelosses. This study focuses on analysis of MOs for developing turbulent flows. A large number of experimentswere performed, exploring the number of holes (n), Equivalent Diameter Ratio (EDR), compactness ratio (C),plate thickness ratio (s/d) and upstream developing length (L/D) in the Reynolds number (ReD) range of24,500-55,500. An empirical correlation of pressure loss coefficient and flow rate is formulated. It isobserved that pressure loss coefficient decays with the fourth power of EDR. A comparative study of theexperimental data with the literature is presented to ensure consistency and reliability.
