Question

Principle behind winnowing is:
(a) Difference in densities of components
(b) Difference in color of components
(c) Difference in appearance of components
(d) Difference in shapes of components

Answer 1

Explanation:

Principles behind winnowing are:

a) Components of density are: mass and volume, both of which can be more confusing than at first glance. An application of the concept of density is determining the volume of an irregular shape using a known mass and density

b) Components of Color:

There are 3 types

1) Hue: the dominant wavelength, the redness of red, greenness of green, etc.

2) Saturation: the purity of the color, or how much white is contained in the color. For example, red and royal blue are more saturated than pink an d sky blue, respectively.

3) Luminance (intensity, value): the intensity of the light.

c) appearance of components: Developed formulations were evaluated in terms of physical appearance, stability and adhesiveness

d) Component Shapes:

Each of the ~200 component shapes within Simergy have been created so that they will be recognizable by the shape alone to the engineering community and may be similar to shapes that they have used to create system designs for projects. Almost all of the EnergyPlus objects outlined with the Input Data File (IDF) format have a shape associated with them. In some cases one shape, such as the chiller shape, will represent multiple IDF EnergyPlus objects. Since there is no one standard for component shapes a number of sources were references for creating an appropriate shape, such as the ASHRAE Fundamentals Handbook and different engineering design team’s drawing set. In other cases, new shapes were created because shape precedents could not be located. Overall, the intent is that the engineer could describe or review the system design configuration by just looking at the component shapes alone.

I hope it is helpful to you.
