Female lice can lay up to 8 eggs per day but usually 5 per day is the average.
Windsock (primarily used to indicate wind direction, may also be used to estimate wind speed by its angle). Pitot tubes is a pressure measuring instrument used to measure fluid flow velocity, and more specifically, used to determine the airspeed of an aircraft. Remote sensing techniques:eteorological instruments to measure wind speed and/or direction. In meteorology wind direction is reported by the direction from which it originates. For example, a northerly wind blows from the north to the south.
Make and Use an Anemometer to measure Wind Speed Overview Wind is the horizontal movement of air. The instrument used to measure wind speed is called an anemometer, which is an indicator that will spin in the wind.The anemometer rotates at the same speed as the wind. It gives a direct measure of the speed of the wind.Wind speed is measured by using the Beaufort Wind Scale which is a scale of 0-12 based on visual clues. Depending on the ability of students, it is probably sufficient that they recognize calm air, and gentle, moderate, and strong breezes.t gives a direct measure of the speed of the wind.
