6522. Various efficiencies of a centrifugal pump are related as (where, ηm = mechanical efficiency ηv = volumetric efficiency. ηma = manometric efficiency ηo = overall efficiency) September 7, 2025 by Admin ηma x ηm x ηv = ηo ηm = ηv . ηma ηma = ηm x ηv ηv = ηm x ηma ✅ The correct answer is option B.
