Total Number of Iterations taken for Simulation = 500

CUT PLOTs Obtained for Velocity:

(A) Outlet Velocity = 10 m/sec:

(B) Outlet Velocity = 20 m/sec:

MASS FLOW RATE:

PLOT of Mass Flow Rate vs Pressure Ratio:

RESULT Discussion:

From the above plot, it is observed that Mass Flow Rate increases with decreased Pressure Ratio. In the boundary condition,the Outlet Velocity is increased from 10 m/sec to 30 m/sec for the parametric analysis of the Pump. Thus Pressure Loss also increases due to more friction. So, Pressure Head and Pressure Ratio decrease with increased Velocity.

NB:  In addition, if Recirculation Loss occurs due to difference in Blade Angle and Flow Angle; then the Performance Curve may look different from the above one. In that case, Pressure Ratio slightly  increases and then comes down with increased Velocity and Mass Flow Rate.Again for the Other Losses, the Curve Nature may change.

So, the Nature of Performance Curve depends on the Pump Parameters.
