How can an aneroid barometer give reading in inches of mercury when it doesn't use any mercury?
Good question.Look at it like this if you had two barometers side by side, one a mercury barometer and the other a barometer that reacted to changes in air pressure using some bellows and a spring.Then, as the pressure changed you marked the second barometer positions and noted on the dial the inches reading from the mercury barometer, the second barometer measurement scale would mimic the real mercury barometer even though it did not actually use any mercury.
What would you give to a person that loves reading?
A book
What instrument would give a reading of 53 percent?
humidity meter
Would a bad fuel pressure sensor give a negative pressure reading?
NO it will not.
What is an ivory point in fortins barometer?
The ivory point in a Fortin barometer is a short (typically about 1 cm) conically-shaped piece of ivory positioned with its apex pointing vertically downwards just above the surface of the mercury in the barometer's reservoir. It is positioned accurately during manufacture so that the tip of the ivory is in exactly the same horizontal plane as the zero mark of the scale which measures the height of the mercury column, and is known as the Fiducial Point. Before reading the height of the mercury column, a user of the baromerter adjusts the level of mercury in the reservoir until its surface just touches the ivory point, at which level the height scale will give an accurate reading.
What is the purpose of home weather stations?
Home weather stations are very interesting to have in your home. They give you the daily temperature, barometer reading, humidity, outside temperature, sunny or rain conditions. They are very informative and can be used as a teaching tool for children studying weather in science.
How can you determine air pressure?
Air pressure is usually measured using a barometer. This device usually has mercury inside it along a tube that is a compete vacuum. As the air pressure rises the pressure of the air pushes down on the mercury and forces it to rise further into the vacuum. 760 mm of mercury is considered to be 1 atmosphere. For very high pressures an aneroid barometer is used. This has wafers inside that are compressed under high pressure that give a reading.
What effect would injecting insulin have on the results of the test?
The insulin would regulate the blood glucose level and this will give the correct reading.
Does reading give you softer hands?
No. However, people whose hobby is reading are likely to have softer hands than people whose hobby is working on cars. Reading doesn't directly make your hands softer, but it does take up time that you might otherwise spend on activities that would give you more calloused hands.
How does digital barometer work?
I bought a digital weather station recently so I've been studying the various features one of which is a digital barometer. This particular one lets you set the altitude of your house for greater acuracy. A barometer's range as I understand it is from 28 to 32 inches. When the barometer falls it is indicating a change in the weather such as rain or a storm. The lower the number goes the more severe the storm. When it rises it indicates that better weather is coming. Remember, though, a barometer tells you what the weather will be not what the weather is. My instrument seems to predict what the weather will be in about 12 hours with a fair amount of acuracy. By the way the unit I bought was a relatively inexpensive one from Radio Shack and it seems to be fine
