In this study. the flow in a 5-bladed centrifugal pump within vaned and vaneless diffuser is analyzed numerically. The method contains of assumption as steady. incompressible and viscous flow solved according to 2-D Navier-Stokes equations relating finite volume technique. https://www.bekindtopets.com/special-deal-2025-Armada-Tantrum-Junior-Skis-with-Atomic-Colt-7-Bindings-super-save/
