This paper presents a non-traditional perspective of energy transfer in turbomachinery. Two different kinds of energy are present. One is a kind of invisible imaginary storage energy that stores energy on the acted material and the other is a kind of visible real working energy that does not store the energy on the acted material but acts on the material to move it and do the work in the direction of action. Their acting directions are normal to each other. Their fundamental interrelation and the interrelation with the blade angle of centrifugal pump are theoretically discussed. Experimental test results are also shown in this paper.
