The production of sound during speech or singing is a complicated process. Let's concentrate on the mouth. A typical depth for the human mouth is about 7.4 cm , although this number can vary. (Check it against your own mouth.). We can model the mouth as an organ pipe that is open at the back of the throat.

a) What are the wavelengths of the first four harmonics you can produce if your mouth is open?

Express your answers in centimeters separated by commas.

b) What are the frequencies of the first four harmonics you can produce if your mouth is open? Use 351 m/sm/s for the speed of sound.

Express your answer in hertz separated by commas.

c) What are the wavelengths of the first four harmonics you can produce if your mouth is closed?

Express your answers in centimeters separated by commas.

d) What are the frequencies of the first four harmonics you can produce if your mouth is closed? Use 351 m/sm/s for the speed of sound.

Express your answer in hertz separated by commas.

The steam used during the production of alumina in the Bayer process serves as both a heating and process fluid. Some steam is recycled, but some is condensed, clarified, and used for hot water in the plant before being cooled in a forced draft cooling tower and discharged.Most of worldwide bauxite mining and alumina production takes place in Jamaica. Therefore, the source of process water for most plants is the Caribbean Sea. Seawater is desalinized and sent as “slightly saline”...

Manufacturing integrated circuits is an enormously complicated task, as there are many process variables that can be manipulated (thickness of this, width of that, doping level of something else, etc). Generally speaking, many copies of a circuit are put onto a single wafer, which is made all at once. We have an experiment where we are varying two factors, each at two levels. We have 20 wafers and assign each of the four factor/level combinations to five wafers at random...
