Wageningen Propeller: B5-60
Wageningen B-series ship propeller open-water characteristics — thrust coefficient KT, torque coefficient KQ, and open-water efficiency eta_0 as functions of advance ratio J for six series designations (B3-50, B4-55, B4-70, B5-60, B5-75, B6-80) at pitch-diameter ratio P/D=1.0. Computed from the Oosterveld & van Oossanen (1975) polynomial regression equations. Used for ship powering calculations, propeller selection, cavitation assessment, and hull-propeller interaction studies.
