    No full text
    ABSTRACT A rigorous derivation of the K = Cp i -Cp diffuser recovery and loss equation is presented and the critical assumptions to yield this simplified relationship are critiqued. Confirmation of the equation is achieved using precise laboratory data and a new diffuser loss-map is presented which facilitates engineering diffuser design work, even when a Kline-map is unavailable. Numerous application examples for turbomachinery analysis are given
