If an impeller has few blades i.e high pitch it will result in less lift force and in a similar manner for more blades i.e. very low pitch, there will be high drag force. Visa mer Blade solidity is an important design parameter for the axial flow impeller and is defined as the ratio of blade chord length to spacing. • Blade Solidity = c/s Where Visa mer Design of the impeller depends on specific speed, hub-tip ratio and solidity ratio.
