Web3 okt. 2014 · The system has an 8-in. exhaust duct. The area of an 8-in. duct is .35 sq. ft. You measure the velocity at a points in the duct and find the average velocity in the exhaust duct is 400 FPM. Multiply 400 Feet per Minute times the area of the duct, which is .35 square feet, to find 140 CFM exhaust fan airflow. 3. Plot Fan Airflow Web25 apr. 2024 · The cup or rotational anemometer is one of the oldest types of anemometers. The cups are placed onto a vertical axis, and when the wind presses against them, this causes the cups to rotate around. The faster the cups rotate, the faster the wind speed. Cup anemometers usually have digital readouts.

WebUltrasonic Anemometers are the ideal sensors for general meteorological applications requiring no moving parts for low-maintenance or measurements with fast response even in very low-range wind speed conditions. Model DNB205 (serial output) is a compact size sensor very suitable in lite weather stations. DNB305-305.1 (serial output) are made in … WebThe advantage of hot-wire anemometry is associated with its very high spatial resolution and excellent frequency response characteristics. In most cases, the probe-stem is perpendicularly aligned with the mainstream direction of flow. A particular type of hot-wire is given in Fig. 4.3.
