出版：International Organization for Standardization
专家解读视频
This International Standard specifies a method for the determination of the volume flow-rate in a closed conduit by means of the velocity-area method using propeller-type current-meters under the following conditions: a)the velocity distribution is regular (see6.1.2); b)the fluid is water which is clean or considered to be clean1); c)the conduit is full; d)the flow is steady2).
