WebIn evaluating a measurement method, psychologists consider two general dimensions: reliability and validity. Reliability Reliability refers to the consistency of a measure. WebThis is a useful principle for making flow measurements, as will be demonstrated below. Here is an example of a computation of flow using the continuity equation. The velocity is measured as 10 feet per second and the cross sectional area of the flow is measured as 10 square feet. Flow = 10 feet per second * 10 square feet = 100 cubic feet per ...
