Transcribed Image Text:**Outside Engineering Building**
This table displays measurements of humidity variables gathered outside an engineering building. The leftmost column lists the various humidity variables, while the subsequent columns represent individual measurements and their average.
| Humidity Variable | Individual Measurement | Average Measurement |
|--------------------------|------------------------|---------------------|
| T (°C) | 20, 30, 20, 16, 14 | 20 |
| Tw (°C) | 13, 16, 15, 14, 14 | 14 |
| Td (°C) | 7, 5, 12, 13, 14 | 10 |
| Vapour Pressure e (mb) | 10, 8.7, 14, 15, 16 | 12 |
| Dew Point Depression | 7, 14, 5, 2, 0 | 6 |
| Relative Humidity (%) | 43, 20, 58, 80, 100 | 52 |
**Explanation of Terms:**
- **T (°C):** Temperature in degrees Celsius.
- **Tw (°C):** Wet-bulb temperature in degrees Celsius.
- **Td (°C):** Dew point temperature in degrees Celsius.
- **Vapour Pressure e (mb):** The pressure exerted by water vapor in the air, measured in millibars.
- **Dew Point Depression:** The difference between the air temperature and the dew point temperature.
- **Relative Humidity (%):** The amount of moisture in the air compared to what the air can "hold" at that temperature, expressed as a percentage.
Transcribed Image Text:**Inside the Engineering Building**
This table provides an overview of various humidity-related measurements taken inside an engineering building. The data includes individual measurements and average group measurements for several variables.
| Humidity Variable | Individual Measurement | Average Measurement Group |
|---------------------------------|-------------------------------|---------------------------|
| **T(℃) measured** | 20℃, 38℃, 30, 36, 30 | 30.8 |
| **Tw(℃) measured** | 14℃, 36℃, 18, 35, 28 | 26 |
| **Td(℃)** | 10, 35, 10, 34, 27 | 24 |
| **Vapour Pressure e (mb)** | 12, 59, 12, 56, 95 | 30 |
| **Dew Point Depression (℃)** | 6, 2, 12, 1, 2 | 4.8 |
| **Relative Humidity (%RH)** | 51%, 88, 29, 94, 85 | 68.2% |
- **T(℃) measured**: Represents the actual temperature readings inside the building in degrees Celsius.
- **Tw(℃) measured**: Indicates the wet-bulb temperature, which helps in understanding humidity levels.
- **Td(℃)**: The dew point temperature captured, indicating moisture saturation in the air.
- **Vapour Pressure e (mb)**: The pressure exerted by the vapor present, measured in millibars.
- **Dew Point Depression (℃)**: The difference between the temperature and the dew point.
- **Relative Humidity (%RH)**: The percentage of humidity level relative to the maximum that the air can hold at the same temperature.
The average group measurement provides a general consensus of the indoor climate within the engineering building.
