how did you construct the pump curve? how did you obtain the value for plotting the graph, what I mean is the data for capacity and head for every value
AT 30:30 ROI in a nutshell the diagram shows GREEN lines coming straight into the pump - is this accurate....is there actually any CFD paying attention to this water because; to the best of my knowledge the water Swirles in a vortex some time before it enters the impeller domain... is this right or does the water truly shoot straight into the EYE Tangent to the rotational plane? this is a very important point because ALL WATER Swirles down pipes rotating in one direction or another with few exceptions and sometimes reverses or becomes turbulent after bends or 90° elbows or U-Turns. it seems that the inlet rotation of the fluid would be a very important issue that could greatly effect pump performance; especially with respect to cavitation .... A pump with a slight rotation in the same direction as the impeller could greatly reduce the cavitation "Shock" at the leading edge and a rotation opposite of the impeller would increase the pressures at the point of impeller contact.....Please help on this point. Thank you

good stuff my friend !
good stuff my friend ! God bless you !

... fantastic work!
How to change exit blade angle in designing process of software like autocad,solidworks.. please tell
great video

in the minute 26 you wrote that the flow rate is 756 cubic meters/s its segnificantly big you sure about it ?
Ha ha Yes My eyes popped out for a second but then I thought he said .....um .... per hour...? not sure
What was beta 1 for that impeller with beta 2 of 33*?
