1-Which pressure measuring device would you recommend to someone who needs to measure the pressure in a home gas cylinder before usage, and why?

2- Which pressure measuring device would you recommend to someone who needs to measure the pressure of a vacuum cleaner, and why?

Expert Solution

1. I recommend U-tube monometer to measure the pressure of the gas cylinder. Because U-tube monometer is measure the gauge pressure of the cylinder. We can use the gas up to the inside pressure of the cylinder is equal to atmospheric pressure. So we should measure gauge pressure of the cylinder and gauge pressure of the cylinder is measured by the U-tube monometer.

2. I recommend vacuum gauge to measure the pressure of the vacuum cleaner. Because vacuum gauge measure the vacuum pressure. It means how much pressure is law with respect to atmospheric pressure. It is batter to use vacuum gauge to compare the different pressure of the vacuum cleaner.

A device called an interferometer is able to measure small changes in distance by measuring the degree of interference between two beams of light. Two coherent beams of light are split off a laser with a frequency of 272500 GHz and travel slightly different paths through space. When you start your experiment the beams from the different paths of the interferometer interfere constructively when combined. You place piece of a transparent 0.250 micron thick slice of an unknown material so...

An aneroid sphygmomanometer is a mechanical device used to measure blood pressure. A simple random sample of these devices is tested for accuracy and the errors (mm Hg) are listed below. One of the devices is considered to be unacceptable if its error is more than 3 mm Hg. The criterion for concluding that the sample is from a population of unacceptable devices is σ >1.5 mm Hg. Use a 0.10 significance level with the sample data to test the...
