Centrifugal pump design and analysis

Objective

To design centrifugal pump and obtain the relationship between Pressure ratio and mass flow rate.

Design

Case study 1 (Velocity - 10m/s)

Cut plot

Flow trajectories

Case study 2 (Velocity - 15m/s)

Cut plot

Flow trajectories

Case study 3 (Velocity - 20m/s)

Cut plot

Flow trajectories

Case study 4 (Velocity - 25m/s)

Cut plot

Flow trajectories

Case study 5 (Velocity - 30m/s)

Cut plot

Flow trajectories

Performance diagram

In the above plot we clearly see the veriation of pressure ratio with respect to mass flow rate
