Abstract: In the analytical theory, a fluid loss caused by biased flow around the impeller was proposed. The upper limit of the solidity on linear design was 2.5. The total pressure of the fan based on the analysis of the fluid loss was estimated with a reasonable validity. When the solidity of the impeller was designed large, the total pressure of the fan at the same operation point became low. The slip factor and the fluid loss of vortex flow changed corresponding with the solidity. It was experimentally proved the influence of the slip factor on the total pressure of the fan was greater than the total fluid loss.
