Humidity Calculator

Relative humidity calculator

Free Professional Online HUMIDITY CALCULATOR

The warmer the air the greater the quantity of water vapour it can contain. Water vapor pressure is the pressure exerted by a water vapor that is in equilibrium with its non-vapor phases. Direct measurement of mass flow or standard volumetric flow in compressed air and non-corrosive gases. Accuracy water analysis calculation. Rounding Weight Total number of digits to show when rounding.

Frost point is the temperature at which frost forms, on cooling a gas. Most damage to older products is caused by air humidity fluctuation.

If partly saturated air is cooled without changing its pressure or amount of water vapour, a point is reached when it becomes saturated. Pressure Units The unit of measurement of the sample pressure.

Temperature Dewpoint and Relative Humidity Calculator

There appears to be a direct relation between relative humidity and phsychological wellfare of humans. The Relative Humidity and Mixing Ratio are calculated from the values input. Dew Point Best dew point measurement accuracy and long-term stability due to special auto-calibration feature.

When it is cold, a higher air humidity makes people believe it is warm. The humidity calculator calculates the frost point from the inverse water vapor pressure formulae, wolverine game selected by user.

Wet-bulb temperature is the temperature indicated by a thermometer sheathed in a wet wicking, and influenced by a rate of evaporation from the wicking. Michell Humidity Calculator Settings Displayed results. Molecular Weight Calculator. Products Differential Pressure Sensor. This can be a fixed device for meteorology or a handheld sling psychrometer that is often used in air conditioning applications.

Sample Temperature The temperature at the point where the humidity measurement is made. Absolute humidity is the mass of the water vapor present in unit volume of moist gas of a given temperature and pressure. The actual amount of moisture known as the mixing ratio is measured in grams of water per kilogram of dry air.

Relative Humidity (RH) Calculator

Since evaporation takes up heat, the thermometer will cool to a lower temperature than a thermometer with a dry bulb at the same time and place. An Explanation of humidity calculator measurements you can find here. Pressure Compensation If conversion to another pressure is required, enter that pressure in this box. In practise, one should adopt a worst-case scenario. It is also the temperature, at which water vapor is in equilibrium with liquid water.

Air Velocity More about Air Velocity. The resulting humidity measurements are displayed immediately, subject to changing ambient conditions. Press Information Press releases Press photos. If the dry and wet bulb temperatures are set to the same value the calculator will show the saturation mixing ratio the amount of water in saturated air at that temperature.

Relative humidity

Psychrometer Coefficient Psychrometer coefficient for wet bulb calculations. According to this method, one can determine how much moist a moisturizer must spray. Questions about our products? How much moist must be added to this air? Defaults to atmospheric pressure.

Humidity calculator - dewpoint calculation and conversion of humidity

As temperatures increase, relative humidity decreases. Langelier index calculator. Hardness Converter and Hardness Calculator.

Temperature Units The temperature units to use for all temperature parameters including sample temperature, dew-point, frost-point and wet bulb. They are ideal for measuring the differential pressure in ventilation and air conditioning systems or for filter monitoring. Parts Per Million ppm Converter. Gas Type Choose from a list of preset molecular weights. The simple and intuitive operation of the humidity calculator facilitates the work.

Naturally, this can all be controlled by a Mollier diagram. Additionally to air, the devices can also be employed for all non-flammable and non-aggressive gases. Calculated water vapour pressure is negative.

Review Article Meteorologische Zeitschrift, N. Flow Direct measurement of mass flow or standard volumetric flow in compressed air and non-corrosive gases. Mixing humidity ratio is the mass of water vapor per unit mass of dry carrier gas with which it is associated. Enthalpy is a measure of the total energy in a humid gas.

Temperature Dewpoint and Relative Humidity Calculator

The air temperature is measured with a normal thermometer this is the Dry-Bulb reading. The humidity calculator calculates the dew point from the inverse water vapor pressure formulae, selected by user. Enter temperature values and atmospheric pressure then press the Compute button to display the output here.

It is also the temperature, at which water vapor is in equilibrium with ice. Temperature Unit Conversion. Most materials give off or take up moist.

Known Value The value of the known parameter. This can cause damage to a material or product. The moisture will be given up as dew or ice crystals. Principally, when air is warmer, it can contain more fluids.

Moist gas density is the mass of the moist gas in unit volume of moist gas of a given temperature and pressure. Meteorological reports usually quote the temperature and dew point as well as the station pressure. Calculated water vapour pressure higher than total pressure. The amount of moisture air can hold is dependent on its temperature and pressure.
