In order to prepare a large-scale test facility, a large test yard and enormous cost investment are required. Therefore, in reality, such a sufficient test environment cannot be prepared. In the field test where equipment is brought into the field such as a lake or marsh, the area where the predetermined flow velocity value is cleared, that is, the stirring capacity range is measured, or the field test etc. If not, measure the reaction force F (axial thrust) from the submerged mixer at the time of water supply drive, and based on the reaction force F of the measurement, the general relational expression “F (reaction force) = ρ (density ) X Q (flow rate) x v (flow velocity) ", there is a method to simply calculate the flow rate Q and estimate the stirring capacity range, but in any case, it is not possible to easily check the stirring capacity range with high accuracy. from without preparing a large-scale test equipment, without the need for enormous cost investment and extensive testing yard can easily identify the top stirrer repertoire accurate, provides a feed water test apparatus in water mixer That is.
