how do you use a davis anemometer.  Not the high speed.?

I did a google and there are different models, so I'm not sure which one you need info about. But, the photo of the model at the site below looks pretty simple--as if you merely hold it in the path of the airflow, and read the speed of the wind. It says the model is intended for students.

tried this problem, but when converting 2cm disance to meters, the acceleration was way out, too large.I used the equation V2 = U2 + 2aS to arrive at the acceleration (deceleration). This might have been the wrong approach.

A hand held instrument called a velometer. It measures the pressure of the air against a tube and gives a digital readout. Feet per second, Meters per sec.

Very wet!\n\nTry it yourself.  Take a sprinker head and put in on a hose up as high as you can support it.  Place a bucket below.  Turn on the water and adjust it until you get your 1.5 inches per minute in the bucket.  \n\nGo stand in the flow.\n\nVery wet!

Just set it to field altitude when on ground. Then compare bar pressure reading on alttimeter to current pressure from weather station. If they are the same you areOK

If you are asking how to measure temperatures this cold (practically), you would use a T thermocouple.\n\nhttp://instserv.com/rmocoupl.htm

if you are asking an instrument to measure a parameter outside of its design range, then it is not possible to state with accuracy how reliable the measured value is.  Your best bet is to look at the equations for flow through an orifice and see if the pressure drop is linear, or not, or what the relation is.  You might be able to extrapolate a resaonable approximation of the true flow if it is not too far away from the 3000 value.  If the meter was reliable below 3000, the manufacturer would have stated so.

You could try to make an accurate experimental thermometer by glueing two strips of dissimilar metals together along their lengths. Perhaps try copper and steel or copper and aluminum or steel and aluminum.  Try perhaps one half inch wide by six inch long strips.  Use sheets of metal that are equally thin.  Perhaps cut the strips from aluminum soda cans and steel soup cans, etc.  Use a magnet to check for steel vs aluminum.  Glue the strips together using epoxy or super glue.  Attach one end of the combined strip to a firm base and leave one end free to move in front of a paper scale.  You now have a bimetalic thermometer.  The thermometer can be made to be more sensitive by using greater length strips and bending the strips into a spiral and attaching a pointer to the free end of the spiral to amplify movement.  This is how most oven thermometers are built except the metals are joined without glue.  The principal of operation of a bimetalic thermometer is that one  metal expands or contracts more or less than another metal.  When joined, a temperature change causes the combined strip to bend.  You can calibrate your thermometer by marking its "pointer" position at two or more large temperature changes then calculating the total deflection divided by the total temperature difference to get deflection per degree (either F or C).  Be careful with tin snips and epoxy or super glue.  Good luck.\n\nAs an alternative, you can make a highly accurate experimental thermometer by winding very thin insulated copper wire (like that used in toy motors) around a wooden spool and connecting the scraped   wire ends to an accurate ohmmeter to measure resistance change vs temperature change.  Calibrate as before but remember that calibration temperatures must be steady long enough for any lag to catch up.  This is called a resitance thermometer and accuracy will depend on the length and thinness of wire and sensitivity of your ohmmeter.  Also the ohmmeter should not cause enough current to flow in the wire to heat the wire.  Observe for drift (increase in resistance and temperature) while taking measurements.

Last summer at the tv station I interned with, one of the meteorologists went in a wind tunnel to show what wind speeds in a hurricane are like.  I just found the video on their website - \nat 95 mph: "I don't know how any human being could remain on their feet if they tried to move at all."\n108 was all he could make it up to because it was too hard to breathe.

If the antenna is mounted the best way is to use a plumbob and a bubble level gauge. Or just the bubble level gauge with degree increments labeled. another way is to use a compass and a square against the front of the antenna. Hope this helps.

This is a bit complicated but you might try this....\n\nStart with a centralized heat source, preferably electrical, so it should remain fairly constant.  You will need three thermometers, each to be held in place by their own stands.  Place a block or bar of metal so that it does not quite touch the heat source, and in contact with its thermometer at the far end.  Place a wooden bowl with water (a metal or glass container would taint your study ) near the heat source with its thermometer just in the water.  Place your last thermometer the same distance from the heat source, thus testing the heat conductivity of air.  If you had access to more thermometers and stands, you could place them at various points in a line from the heat source.  You will notice that the last thermometer will by far have the lowest readings.

With an anemometer is like three sticks with a little cup on each end, arranged at 120° at the top of a pole wich rotates faster or slower depending on wind speed. You can see them at ships and airports...
