FAQ: How To Make An Anemometer For A Science Project?

What materials do you need to make a anemometer?

Materials:

  1. 5 small paper cups.
  2. Hole punch.
  3. Scissors.
  4. Duct tape.
  5. 3 thin wooden dowels.
  6. Empty water bottle.
  7. Stopwatch.

How does a homemade anemometer measure wind speed?

Use a red marker or red paint and put a large X on one of the cups. Take your anemometer outside and measure the wind speed. To do so, count the number of times the cup with the red mark passes in front of you in 30 seconds. Multiply by two to get revolutions/rotations per minute (rpm).

How does a homemade anemometer work?

Each cup is attached to the end of a horizontal arm, each of which is mounted on a central axis, like spokes on a wheel. When wind pushes into the cups, they rotate the axis. The faster the wind, the faster the cups spin the axis. How fast will your homemade anemometer whirl?

How do you measure wind speed without an anemometer?

A much simpler way to measure wind speed is with a ribbon tied to a stick. Once calibrated, the device will allow the casual kite-flyer or sailor an indication of the wind speed. Place the three ribbons on top of each other and tie them together on one end.

How can you predict wind speed?

All wind predictions are based on those systems. In predicting wind there are a number of things that forecasters will look at: the position of the high and low pressures, how intense they are, how they interact with each other and the local topography, and, since we live in a 3-D world, altitude.

How do you calculate wind speed?

Calculate a miles per hour wind speed in feet per hour, then divide by the number of feet in a knot. For the example wind speed of 100 mph, do as follows: 100 mph x 5,280 feet = 528,000 feet per hour; 528,000 feet per hour/6,080 feet = 86.8 knots.

What is the tool that measure temperature?

A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin.

How do you make a weathervane?

Cut an arrow and a tail out of construction paper, then slip them into the slits on the straw. Place a piece of clay in the center of the cardboard, and stick the tip of the pencil into the clay. Use a pin to fasten the straw to the top of the eraser. Make sure it’s centered.

What is the jet stream which direction does it flow and approximate wind speed?

How the earth’s rotation effects the west to east direction of the jet stream. Jet streams are relatively narrow bands of strong wind in the upper levels of the atmosphere. The winds blow from west to east in jet streams but the flow often shifts to the north and south.

How is wind speed and direction measured?

Anemometers measure wind speed and wind vanes measure wind direction. A typical wind vane has a pointer in front and fins in back. When the wind is blowing, the wind vane points into the wind.

How do you read wind speed and direction?

Wind direction can also be reported as a compass degree. There are 360 degrees on the compass, with north being 0 or 360 degrees and south 180 degrees. Wind speed is indicated by feathers added to the top of the staff. These feathers show wind speed adjusted to the nearest 5 mph increment.
