Musical Scales and Intervals

For example, an octave is a music interval defined by the ratio 2:1 regardless of the starting frequency. From 100 Hz to 200 Hz is an octave, as is the interval from 2000 Hz to 4000 Hz. The intervals which are generally the most consonant to the human ear are intervals represented by small integer ratios.

Concrete Mix Ratio: What Is It? What Is 1-2-3? ...And …

 · A concrete mix ratio is usually expressed by a set of numbers separated by colons, as is the case with a 1:2:3 ratio. This tells the mixer that they need to add 1 part cement powder, 2 parts sand, and 3 parts aggregate in order to create the desired concrete consistency. Water is not included in these ratios, though, because it can vary more ...

Lecture 4: Mining waste

The ratio between waste rock and ore production is called the stripping ratio. For example, a stripping ratio of 2:1 means that 2 tonnes of waste rock needs to be mined to mine 1 tonne of ore. Generally, an open pit mine has a higher stripping ratio than an underground mine.

Mobility Ratio

If the mobility ratio is small enough, a definite front of mobile oil develops in front of the advancing water. The displacement is not an exact, piston-like process; instead, an oil saturation gradient exists from S o = 1 – S wc in the mobile oil to S or at the zone of injection where a large volume of water has contacted the porous medium, shown in Fig. 3-7 .

Crusher Reduction Ratio

 · Crusher Reduction Ratio I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged.

Poisson''s Ratio

Essentially Poisson''s ratio is one measure of a rock''s strength that is another critical rock property related to closure stress. Poisson''s ratio is dimensionless and ranges between 0.1 and 0.45. Low Poisson''s ratio, such as 0.1–0.25, means rocks fracture easier whereas high Poisson''s ratio, such as 0.35–0.45, indicates the rocks are harder to fracture.
