Where should wind speed sensors (anemometers) be positioned in a tunnel-ventilated closed layer house to measure the average wind-chill effect?

In tunnel-ventilated closed layer houses, wind-chill cooling is the primary defense against heat stress. To get an accurate and representative measurement of air velocity, wind speed sensors (anemometers) must be placed in the center of the house, approximately 1.5 meters from the floor (representing the average height of birds in a multi-tier cage system). Placing sensors too close to the exhaust fans will result in artificially high speed readings due to localized turbulence, while placing them directly next to sidewalls or inlet pads will show lower speeds due to frictional drag. Wind speed must be kept around 2.5 to 3.0 m/s for maximum cooling. Ventilation engineers can study aerodynamic modeling in the Poultry Encyclopedia, buy professional handheld and digital anemometers on Poultry Plaza, monitor egg rates on Poultry Rates, and trade closed house equipment on Murghi Mandi.
