【Abstract】 A new method for determining the outlet width b2 of centrifugal pump Im-peller is proposed based on the principle of minimum power loss. It is for the centrifugal pump with specific speed ns>80. For those with ns 80, the formulae for calculating the outlet parameters b, and D2 are also discussed.更多还原
