Centrifugal Pump Design

Overview

This skill provides a comprehensive workflow for designing centrifugal pumps from first principles using Euler turbine equations, velocity triangles, and dimensionless parameters. The methodology follows classical pump design theory as presented in Stepanoff, Gülich, and Karassik.

Design Workflow

1. Requirements Analysis

Input Parameters:

• Flow rate: Q (m³/s or m³/h)
• Head: H (m)
• Rotational speed: N (rpm)
• Fluid properties:
  • Density: ρ (kg/m³)
  • Kinematic viscosity: ν (m²/s)
  • NPSH available (m)
