    What Will Be The Rate Of Transpiration When Temperature Increases

    The rate of transpiration is one of the most important factors in regulating your body’s temperature. When the temperature rises, the body mobilizes more blood to the skin in order to cool down. This results in a higher rate of transpiration. In order to properly prepare for this dramatic temperature change, be sure to keep track of your daily rate of transpiration and adjust your regimen as needed. This will help you stay comfortable and healthy during this hot summer season.

    What Temperature Will Cause A Change In Transpiration Rate?

    A change in transpiration rate will be caused by a change in temperature according to the following equation:

    Rate of Transpiration = (Convective Heat Transfer Coefficient) x (Temperature)

    In general, when temperatures increase, the rate of transpiration will also increase. For example, at 85 degrees Fahrenheit, a person’s sweat rate would be approximately six ounces per hour. At 105 degrees Fahrenheit, the sweat rate would be approximately twelve ounces per hour.

    How Much Will The Rate Of Transpiration Increase?

    When the outside temperature rises, the rate of transpiration (the release of water vapor from plants) also increases. Transpiration is a natural process that helps cool the plant and help to regulate its moisture levels. Generally speaking, when air temperatures increase by about 0.5 degrees Celsius (0.9 degrees Fahrenheit), the rate of transpiration will also increase by about 10 percent.

    What Are Some Other Factors That Can Affect Transpiration Rate?

    There are a few other factors that can also affect transpiration rate. These include humidity, air temperature, wind speed and direction, and body size. Additionally, the type of soil can affect transpiration rate as well.

    Humidity: The level of humidity in the air can have a significant impact on transpiration rate. When the humidity is high, it takes more water vapor to evaporate from the body than when the humidity is low. This can result in a lower transpiration rate.

    Air Temperature: The air temperature also affects transpiration rate. In general, the higher the air temperature, the more water evaporates from the skin. However, this increase in water vapor uptake also leads to an increase in heat production which can trigger sweating (in hot weather conditions) or panting (in cold weather conditions). So while increasing air temperatures will lead to an overall increase in sweat production, it may also cause discomfort if done excessively.

    Wind Speed and Direction: The wind speed and direction can also affect transpiration rate. Strong winds can cause large waves to form on lakes and oceans which causes evaporation rates to be increased considerably (this is why coastal areas tend to be wetter than inland areas). Conversely, calm winds will cause less evaporation because there is little movement of water droplets around objects. So depending on the situation, wind speed and direction may either help or hinder perspiration rates.

    Body Size: Finally, body size plays a role in transpiration rate. While the average person sweats about 1 liters per day, people who are particularly large or small may sweat more or less, respectively.


    In this article, we explore the effects that temperature has on transpiration. We learn that when temperature increases, the rate of transpiration increases as well. This is because when body temperature rises, the hypothalamus in the brain sends chemical signals to the sweat glands telling them to produce more sweat. Ultimately, this increase in sweating will help cool us down by releasing heat from our bodies.
