Flow Velocity

The Flow Velocity Concept Builder investigates the relationship between the cross-sectional area of a flow tube and the velocity at which the fluid flows through the tube. The Concept Builder consists of 44 total questions organized into 12 different Question Groups and spread across three Activities. In the first activity, Case Studies, learners are presented with a diagram of a pipe with a changing cross-sectional area; they must compare the volumetric flow rate and the flow velocity on the latter side to the earlier side of the change. In the second activity, Ranking Tasks, learners are presented with a diagram of three situations involving a change in cross-sectional area or diameter of a pipe. The input velocity, initial area (or diameter) and final area (or diameter) values are given and they must rank the output velocities for the three situations. In the third activity, Law Breakers, learners are presented with three diagrams with values of input velocity, output velocity, and cross-sectional areas. They must identify any of the diagrams that violate the law of mass conservation. Question-specific help is provided for each of the 12 situations. Use of this Concept Builder with our Task Tracker system allows teachers to track student progress.
