rainfall

temperature

relative humidity Correct answer

atmosphere pressure

Answer Details

The factor that is monitored with the use of wet and dry hygrometer in a brooder house is relative humidity. Relative humidity refers to the amount of moisture present in the air, expressed as a percentage of the maximum amount of moisture that the air could hold at a given temperature. In a brooder house, maintaining the correct relative humidity is essential for the health and well-being of the young birds being raised. A wet and dry hygrometer is a simple instrument used to measure relative humidity. It consists of two thermometers, one of which has a wet wick wrapped around its bulb. The wet wick is exposed to the air, and as the water evaporates, it cools the thermometer, causing the temperature to drop. The difference in temperature between the wet and dry thermometers is used to calculate the relative humidity. In a brooder house, the wet and dry hygrometer is used to ensure that the relative humidity is within the appropriate range for the age and type of birds being raised. Too high a humidity can lead to respiratory problems and the growth of harmful bacteria and fungi, while too low a humidity can cause dehydration and other health issues. By monitoring relative humidity with the wet and dry hygrometer, the caretakers of the brooder house can make adjustments to ventilation, heating, and other environmental factors as needed to maintain the optimal conditions for the birds' health and growth.
