What values are plotted on a psychrometric chart?
What values are plotted on a psychrometric chart?
Boundaries of the psychrometric chart are a dry-bulb temperature scale on the horizontal axis, a humidity ratio (moisture content) scale on the vertical axis, and an upper curved boundary which represents saturated air or 100-percent moisture holding capacity.
What are psychrometric charts?
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.
Which are the 5 factors indicated on a psychrometric chart?
Psychrometric Chart
- Evaporative Cooling.
- Dehumidification.
- Dry Bulb Temperature.
- Humidity Ratio.
- Moist Air.
- Wet-Bulb Temperature.
- Desiccant.
- Evaporative Cooler.

What is specific humidity in psychrometric chart?
Use the psychrometric chart to determine the specific humidity ω [18 gm-moisture/kg-air], the enthalpy h [78 kJ/kg-air], the wet-bulb temperature Twb [25.5°C], the dew-point temperature Tdp [23°C], and the specific volume of the dry air v [0.89m3/kg]. Indicate all the values determined on the chart.
What are the 6 psychometric process?
This is the series of articles that describes psychrometric chart and various psychrometric processes like sensible heating, sensible cooling, humidification, de-dumidification, evaporative cooling etc.
What is a psychrometric chart and how is it developed explain any five psychrometric processes and represent them on a psychrometric chart?
A Psychrometric chart graphically represents the thermodynamic properties of moist air. Standard psychrometric charts are bounded by the dry-bulb temperature line (abscissa) and the vapour pressure or humidity ratio (ordinate). The Left Hand Side of the psychrometric chart is bounded by the saturation line.

How do you find the enthalpy of a psychrometric chart?
The enthalpy scale in the psychrometric chart is located outside the main body. The constant enthalpy lines extend from the enthalpy scale down toward the right side of the chart. To find the value of the enthalpy of the any given air, one should know its WB temperature.
How to read a psychrometric chart?
1. Look along the bottom of the chart to find the dry bulb temperature. The horizontal,or “X” axis,of the chart denotes the various temperature
What is psychometric chart?
A psychrometric chart is a graphical representation of the physical and thermal properties of atmospheric air for a particular barometric pressure. Most charts are constructed to be used at a barometric pressure of 101.325 kPa (normal atmospheric pressure at sea level).
What is a psychrometric calculator?
A Psychrometric Calculator is a device that costs to compute the moisture content of the air , commonly this implies the loved one humidity and the dew point. There are many various means that this can be done.
