What is Hygrometric table?

Tables that are set up to easily convert the measured dry- and wet-bulb temperatures to common humidity measures like dewpoint temperature or relative humidity.

What does a psychrometric chart show?

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.

What is psychometric process?

a psychrometric process that involves the simultaneous increase in both the dry bulb temperature and humidity ratio of the air. Cooling and Dehumidifying> a psychrometric process that involves the removal of water from the air as the air temperature falls below the dew- point temperature.

How to check moist air on a psychrometric chart?

Use Figures 2 and 3 with the psychrometric chart in Figure 1 to verify whether you can find each air property. Figure 2. Properties of moist air on a psychrometric chart. Wet-bulb temperature and enthalpy use the same chart line but values are read off seperate scales.

What should the temperature be for a psychrometric chart?

Psychrometric charts are available in various pressure and temperature ranges. Figure 1, is for standard atmospheric pressure (14.7 psi) and temperatures of 30° to 120°F, which is adequate for most greenhouse or livestock housing applications.

What are the boundaries of 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.
