Performance Assessment of a Centrifugal Pump With Varying Blade Counts and Fluid Viscosities Through Euler Head and Entropy Production Analysis

Engineering Reports, Volume 7, Issue 4, April 2025.
The centrifugal pump achieved optimal performance at lower viscosity with a minimal number of blades, as evidenced by reduced turbulent kinetic energy, leading to minimal energy loss and maximum efficiency, with the best operation observed using water and five blades.
