    What is psychrometry?

    Focuses on gas-vapor mixture properties.

    How does humidification differ from dehumidification?

    Humidification adds water vapor; dehumidification removes it.

    What is the purpose of psychrometric charts?

    They assess properties of gas-vapor mixtures at constant pressure.

    What defines wet-bulb temperature?

    Indicates the lowest temperature achievable by evaporative cooling.

    What is the significance of adiabatic saturation temperature?

    Represents the temperature at which air becomes saturated without heat exchange.

    What happens during dehumidification?

    Water vapor condenses into liquid, reducing humidity.

    What methods are used to measure humidity?

    Techniques include hygrometers and psychrometers.

    What is the relationship between wet-bulb and dry-bulb temperatures?

    Wet-bulb is always lower than or equal to dry-bulb in humid air.

    What are the applications of psychrometry?

    Used in air conditioning, cooling towers, and dryers.

    What does a psychrometric chart represent?

    Thermodynamic properties of moist air at constant pressure.

    How is relative humidity measured?

    As a percentage of moisture in the air compared to saturation.

    What is the significance of the saturation curve?

    It indicates the maximum moisture content at a given temperature.

    What happens when air is cooled from 100°F to 75°F on a psychrometric chart?

    The initial and final conditions can be visually represented.

    What is the purpose of the dry bulb temperature?

    It measures the air temperature without considering moisture.

    What does the wet bulb temperature indicate?

    It reflects the cooling effect of evaporation in the air.

    How do you find other psychrometric properties using dry and wet bulb temperatures?

    Locate both temperatures on the chart and find their intersection.

    What is enthalpy at saturation?

    The total heat content of moist air at the saturation point.

    Why is a psychrometric chart useful for heat load calculations?

    It provides quick access to various air properties.

    What does the dew point temperature represent?

    The temperature at which air becomes saturated with moisture.
