The Influence Of The Geometrical Parameters Of Propeller-Type Current-Meter On Its Performance
For many decades, current-meters are used to measure flow velocity in open channels and also closed conduits.
Nevertheless, there is not much information on basic equations of propeller-type current-meter. In this paper, by using
momentum and airfoil theory approaches, we tried to find theoretical equations for driving torque exerted on blades. Then by
equating two obtained equations, the influence of solidity, pitch value and hub to tip radius ratio on full fluid guidanceis
