To find the relative humidity as a percentage from a dry and wet bulb thermometer, it is necessary to record these readings using two standard thermometers and a psychrometric chart. One thermometer measures the dry bulb temperature while the other measures the wet bulb temperature.Know More
To take the wet bulb temperature, place a wet cloth around the bulb and record the temperature reading, which will be lower than the dry air temperature. Similarly, record the dry bulb temperature reading of the air and use the chart to find the relative humidity. A psychrometric chart has the dry bulb temperatures at its base, and the wet bulb temperatures are found on a curved line at the left of the chart. The point where the two readings intersect on this chart is the relative humidity in percent.
An example to find the relative humidity on this chart is using a dry bulb reading of 80 degrees Fahrenheit and a wet bulb reading of 67 F. This will give a relative humidity result of 50 percent.Learn more about Weather & Tides
A humidity level of about 45 percent is considered comfortable outdoors. Levels of humidity can vary from place to place. Humidity levels change according to seasons. Winters are dry and humidity is high in the summer.Full Answer >
Humidity can reduce static electricity. Water conducts electricity, so humidity in the air allows static electricity to leave objects.Full Answer >
There are different tools available to help measure humidity, including a hygrometer, a hygrograph and a sling psychrometer. Each separate tool that measures humidity does so on a different scale.Full Answer >
Higher temperatures make higher levels of humidity possible. This is because warm air is capable of holding more moisture than cold air. Warm air has a stronger bond to water molecules, making the air feel drier and allowing more water to bond with air.Full Answer >
