What are the functions of anemometer?

HistoryThe first anemometer was created by an Italian named Leon Battista Alberti who lived during the Renaissance period from 1404 to 1472. However, the most common type of anemometer was created by Dr. John Thomas Romney Robinson in 1846. It is called a cup anemometer.TypesAnemometers are separated into two different types. Some are for measuring wind velocity and others are for measuring wind pressure. Wind pressure and velocity are related so closely that an anemometer that is designed for one purpose will give information for both.SignificanceMeteorologists can use anemometers to help determine the strength of a storm. Other scientist and climatologists may also use anemometers for a variety of experiments in order to predict future storms or simply to plot a good place for a windmill.ConsiderationsMost anemometers are coupled with other weather measuring tools. Some of the tools used with anemometers are wind socks or weather vanes, which are both used to determine wind direction.Fun FactA simple anemometer can be created using nothing more than a piece of string attached to a ping-pong ball. These balls are very light and move in the wind. If you measure the angle of the ball being moved and compare it to the angle without wind, wind speed can be deduced.


What wind speed causes window glass to break?

Generally speaking, wind speed approaching 80mph may cause windows to break.


What wind speed does a thunderstorm reach?

Many thunderstorms produce very little wind, and wind speeds in most thunderstorms do not exceed 40 mild per hour. In rare cases, though, thunderstorms may produce winds to well over 100 milers per hour.


What is a blast of wind called?

A blast is a violent gust, such as a gust of wind, an explosion, a loud, sudden sound, or an immature or undifferentiated cell.

How wind velocity affects animal activity?

The speed of wind affects how animals hunt. If the wind is very fast, some small animals may find it challenging getting away from their predators, therefore; they have to be extremely cautious.


What is the formula for calculating conveyor belt length?

Equations relating to conyeyor belt length, friction, lag, and velocity may be found at the indicated link(s).


What is the acceleration if velocity is zero?

velocity may be zero or may not be zero i.e. if the object may continue to move with uniform velocity.


What is the velocity if acceleration is zero?

velocity may be zero or may not be zero i.e. if the object may continue to move with uniform velocity.


How do you pronounce perfect wind in Japanese?

In the sense of a wind that feels good, you may say 気持ち良い風, roughly pronounced "kee-moh-chee ee kah-zay."


How do you get area given pressure and velocity?

Velocity is not involved in the definition of pressure, so knowing it doesn't help you calculate pressure. Pressure = force/area You may be talking about wind pressure, which obviously does depend on the speed of the wind, or on the speed of the object through quiet air. In order to know the wind force, you have to know the specific size, shape, dimensions, and surface texture of the object past which the air is moving.

What is the study of the heart using sound waves?

Ultrasonic imaging is the technique of non-invasive examination of the heart and arteries.With refinements of Doppler imaging, the velocity of the blood may be indicated, and the presence of constrictions shown.


How do the velocities of unbalanced weights compared?

When dropped the mass of an object does not affect the rate at which it falls. The size and shape may affect the wind resistance which affects falling velocity but heavier objects will not fall faster than lighter objects with all other variables constant.


What would be the velocity of ball which is thrown by the man who running at the speed equal to the velocity of light?

As velocity never exceeds the velocity of light.... so i hope a man running with the velocity of light will not be able to throw a ball with any velocity.......... we may get the maximum n minimum velocity with which that can be thrown mathematically that we may get it to be zero................


Why is knowledge of vectors important to marine people?

Navigators need to be able to combine the marine vessel's velocity with that of the any currents to arrive at the resultant speed and direction. This requires addition of the vectors representing the velocities of the vessel and of the current. It may also be necessary to add the wind velocity.


What is a very faint wind called?

a breeze. There is no specific wind velocity associated with it, I use it for a localized air movement that may not affect something more than a foot from me (or the thing the air is moving, such as when I see leaves in a tree moving but I can't feel it, or vice versa).
