The dew point temperature lines on psychrometric charts are straight inclined sloping downwards to the right. When relative humidity of moist air is 100%, then_________________?
Correct answer: A. All 'A', 'B' & 'C'
- A. All 'A', 'B' & 'C'
- B. Wet bulb temperature=dew point temperature
- C. Saturation temperature=dew point temperature
- D. Wet bulb temperature=dry bulb temperature
Explanation
At 100% relative humidity, the air is saturated, so dry-bulb, wet-bulb and dew-point temperatures are all equal. The saturation temperature is therefore also the dew-point temperature, making all three statements valid.
