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/mega-super-Paint-Splatter-Purple-iPad-Pro-12-9in-2020-Clear-Case-p23822-must-buy/
