Dewpoint University of Arizona

Dewpoint calculated from: Dry Bulb Temperature Relative Humidity ----- B = (ln(RH / 100) + ((17.27 * T) / (237.3 + T))) / 17.27 D = (237.3 * B) / (1 - B) where: T = Air Temperature (Dry Bulb) in Centigrade (C) degrees RH = Relative Humidity in percent (%) B = intermediate value (no units) D = Dewpoint in Centigrade (C) degrees Here is the same formula, but broken down into smaller pieces: L ...

How to Calculate Dew Point.

Example: Suppose a relative humidity of 55% was recorded in an area with a recorded temperature of 27 degrees Celsius. Calculate the area’s dew point temperature. Therefore, your dew point temperature is 18 degrees Celsius. Share. Tweet. Reddit. Pinterest. Email. Prev Article. Next Article .

Determining the Dew Point of a Gas Sample Interscan

Jun 17, 2012 The corresponding temperature is 46 deg C (114.8 deg F), and that is the dew point of this sample. 4.wheat grinder machine pstone in madhya pradesh Fote Mining Machinery Co. For 20 percent water, a vapor pressure of 152 mmHg would be indicated. By reference to the table, the dew point is seen to be somewhere between 60 and 61 deg C (140-141.8 deg F).

Dew Point Calculator

Welcome to the Dew Point Calculator. Use the sliders to explore combinations of temperature (T), relative humidity (RH), and dew point (DP) to compare the preservation quality of your environment. Knowing the dew point can help achieve long-term preservation of collection materials for libraries, museums, and archives.

Dew Point Calculator Good Calculators

T dew = dew point temperature in degrees Celsius ( C), T = air temperature in degrees Celsius ( C), RH = relative humidity (%), ln = natural logarithm. Example of a Dew Point Calculation. Let's say we have an air temperature of 20 C (68 F) and relative humidity of 70%. We can calculate the dew point temperature as follows: T dew = (237.3 [ln(70/100) + ( (17.27 20) / (237.3+20) )]) / (17.27 - [ln(70/100) + ( (17.27 20) / (237.3+20) )]) T dew …
