Adults: The adult louse is about the size of a grain of rice and has the appearance of an ant. Lice have 6 legs with claws or pinchers at the end of each. Lice are can be dark brown to whitish in color . Lice also have the ability to adjust their hue to better blend in with people who have darker or lighter hair. Male lice are smaller than female lice. 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.
Wind observations are taken at a fixed location using two parameters: wind speed and wind direction. Referenced with respect to true North, the direction that the wind is flowing from is measured in degrees. It also described by the compass points its flowing from (N, NE, NNE, etc.). Wind speed is a measurement of the speed of movement of the air, and is typically reported in miles per hour (mph) or kilometers per hour (kph). Reports for maritime and aeronautical operations may use those or knots (nautical miles per hour). Wind speed and wind direction can be measured with a variety of tools. The most common is the anemometer, which typically consists of a rotating vane to measure direction and a shaft with cups attached that spins with the wind to measure its speed.
