Making a scale drawing (video) | Geometry | Khan Academy

Cole is an urban planner. He wants to create a small scale drawing of a city block. The block is a square with an area of 8,100 square meters. Create a scale drawing of the block using a scale factor of 0.1. So the first thing we could think about, they give us the area of the block. And it's a ...

The design of high-efficiency fans is often based on the experience of the designer. In order to determine its main dimensions, fan designers use the Cordier diagram. For a given operating point (i.e. flowrate and pressure, and a rotating speed), the optimum diameter of highefficiency fans can be found in the Cordier diagram. The Cordier diagram is an empirical diagram based on measurements.

The correlations used for obtaining the Cordier diagram are often not fit for the low Reynolds number and large-gap machines. Therefore, one major weakness in the application of this low-order model to the blade geometry of the blood pumps is that the detailed flow features cannot be properly accounted for.

Theoretical Interpretation of the CORDIER-Lines for ...

For axial, radial and mixed flow fans, a single relationship (CORDIER-diagram) exists and it is well accepted that this line represents "optimum" fan designs with high efficiency. The paper provides a theoretical interpretation of the CORDIER-lines for squirrel-cage and cross-flow fans, since they differ considerably from the classical ...

Aerodynamic Design of Low-Speed Axial-Flow Fans: A ...

The results presented by Cordier in Figure 7 were purely empirical, while Marcinowski in his research on axial fans derived the inclusion of the hub-to-tip ratio inside the same diagram, thus providing a further indication to the designer. Furthermore, the same author addressed the problem of providing an analytic method to compute the optimum ...

Diagram - Wikipedia

A diagram is a symbolic representation of information using visualization techniques. Diagrams have been used since ancient times, but became more prevalent during the Enlightenment. Sometimes, the technique uses a three-dimensional visualization which is then projected onto a two-dimensional surface. The word graph is sometimes used as a synonym for diagram.

A theoretical derivation of the Cordier diagram for ...

The Cordier diagram is an empirical diagram based on measurements. It delivers a relation between flowrate, pressure, rotating speed, and diameter. However, the Cordier diagram does not provide any information on the blade shape (i.e. the angles and the blade width). In order to fill this gap, there are design rules based on the experience of ...
