Measurement of clean water flow in closed conduits - Velocity-area method using current-meters in full conduits and under regular flow conditions
The described method is to be used under the following conditions: a) the velocity distribution is regular; b) the fluid is water which is clean or considered to be clean; c) the conduit is full; d) the flow is steady. Deals in particular with the technology and calibration of propeller-type current-meters, the measurement of local velocities and the calculation of the flow-rate by velocity integration.
