Calculation of centrifugal pump head values with undercutting impeller and changing width of discharge holes
There are presented calculated head values changing with undercutting pump impeller within the nominal supply range. There is revealed a dependence of the pump impeller blade angle on specific speed. Calculations are made for a pump with two-side suction impeller. The estimated results comply with the test ones.
