It is well known that the higher the static pressure, the faster the air will enter through an air inlet and therefore the greater the amount of air which will enter through the inlet. But how precisely does velocity change with pressure and similarly how does the amount of air entering through an inlet change with static pressure? To answer these questions, the performance of typical 44" X 7" (42 ...

A 54" tunnel fan with a 1.5-hp motor is running and consuming 1,700 watts of power. The belt suddenly breaks and the fan blades stop rotating, but the motor continues to spin. How much power do you believe the motor is now consuming? 1,700 watts? It is important to understand that the primary factor determining how much power a fan will use is how fast the motor is spinning the prop. The faster th ...

A poultry house controller's temperature sensors are, in a sense, its "eyes" enabling it to “observe” what is happening throughout a poultry house so it can accurately determine what equipment it needs to operate to maintain the proper environmental conditions throughout a house. As a result, a controller’s ability to maintain proper growing conditions for the birds is only a ...

When designing a tunnel-ventilated house, it is important to install the proper amount of evaporative cooling pad. Too little pad will result in excessive static pressure, which will reduce air speed, and therefore bird cooling. Too much pad will result in increased initial cost, more pads to maintain/replace, and a larger area of reduced air movement near the tunnel inlet end wall.Pad area is bas ...

Using evaporative cooling to keep birds cool during hot weather is relatively simple. Water is circulated over paper pads. Tunnel fans pull hot outside air through the pads and into the house. As the air moves through the wetted pads, its temperature decreases. Fairly straightforward. On the other hand, understanding how evaporative cooling pads lower the temperature of the incoming air can be rat ...

You are frying eggs for breakfast. You get distracted and the next thing you know your eggs are burning and your kitchen is filling with smoke. What do you do first? Open the window to get rid of the smoke or remove the skillet from the stove to stop the generation of the smoke? You of course, remove the skillet from the stove, then open windows because opening the windows in itself doesn't so ...

A fast-growing broiler produces a surprising amount of heat, roughly 10 - 15 Btu/hr per pound of body weight. To put this in perspective, a single match produces one Btu/hr of heat which means that a four-pound broiler has essentially 40 to 60 matches of heat being produced within it. An eight-pound broiler would have 80 to 120 matches of heat within it, heat it must continually rid itself of in o ...
