Calculation:
- Given parameters:
- Inlet air conditions: DBT = 35°C, RH = 50%
- Apparatus dew point = 5°C
- Bypass factor = 15%
Step 1: Determine the coil outlet conditions
- Calculate the coil outlet conditions using the bypass factor formula:
- Tout = (1 - B) * Tdb + B * Tdp
- Tout = (1 - 0.15) * 35 + 0.15 * 5
- Tout = 0.85 * 35 + 0.15 * 5
- Tout = 29.75 + 0.75
- Tout = 30.5°C
Step 2: Check the options for the outlet temperature
- Compare the calculated outlet temperature (30.5°C) with the provided options:
- a) 70°C
- b) 120°C
- c) 9.5°C
- d) 14°C
Conclusion:
- The correct answer is option c) 9.5°C.
