Centrifugal pump design and analysis

AIM
To model and simulate the flow through centrifugal pump and obtain the relationship between pressure ratio and mass flow rate.

SIMULATION
The model is designed.
The flow simulation is also done.
Paramatric study is done with outlet velocity as input and surface goals like mass flow rate and Avg total pressure as output
The graph is generated in MATLAB

CONCLUSION
The ideal graph of mass flow rate vs pressure ratio is parabolic. Here also, for 5 values we observe a decline in pressure ratio as mass flow rate increases, except for 1 reading.
Hence we can say that as mass flow rate increases , the pressure ratio decrases.
The mass flow rate is directly depended on the outlet velocity.
