What do you mean by psychrometric chart?
Psychrometric charts are complex graphs that can be used to assess the physical and thermodynamic properties of gas-vapour mixtures at a constant pressure. They are often used to assess the properties of moist air. Dew point temperature: The highest temperature at which water vapour will condense.
Which are the 5 factors indicated on a psychrometric chart?
About the Psychrometric Chart
- dry bulb temperature.
- wet bulb temperature (also known as saturation temperature)
- dew point temperature.
- relative humidity.
- moisture content (also known as humidity ratio)
- enthalpy (also known as total heat)
- specific volume (the inverse of density)
What does psychrometer mean in science terms?
psychrometer, a hygrometer composed of two similar thermometers. The bulb of one thermometer is kept wet (by means of a thin, wet cloth wick) so that the cooling that results from evaporation makes it register a lower temperature than the dry-bulb thermometer.
What are the components of psychrometric chart?
What is a Psychrometric Chart? Overview of Components
- Dry Bulb (DB) Temperature Lines: The dry bulb temperature scale is shown along the base of the shoe shaped psychrometric chart forming the sole.
- Moisture Content:
- Wet Bulb (WB) Temperature Lines:
- Dew Point (DP) Temperature Lines:
How does psychrometric chart is obtained and what is its significance?
Psychrometric charts show temperature vs. humidity, and can be used to express human thermal comfort, design strategies, and energy requirements for those strategies. Every psychrometric chart includes vertical lines that represent the dry bulb temperatures. Air temperature increases from left to right.
What is psychrometric chart Slideshare?
Psychrometric chart description O Vertical lines are dry-bulb temperature O Horizontal lines are humidity ratio (right axis) or dew point temp (left axis) O Slanted lines are wet-bulb temp and enthalpy O Specific volume are the “other” slanted lines.
What is psychrometer or hygrometer?
The psychrometer, or hygrometer, measures the difference between dry-bulb and wet-bulb thermometer readings. Ref: Pryor, 3. ii. The determination of the psychrometric properties of air at a given state point.
What is the difference between a hygrometer and a psychrometer?
In reality, there is no difference between hygrometer and psychrometer. A psychrometer depends on the oldest method to measure humidity. However, hygrometer uses a totally new digital approach. When it comes to using a hygrometer or psychrometer, the priorities of the department vary.
What is a psychrometric chart show what is psychrometric chart?
A psychrometric chart presents physical and thermal properties of moist air in a graphical form. It can be very helpful in troubleshooting and finding solutions to greenhouse or livestock building environmental problems.
