Given Data:
Dry bulb temperature at the inlet (T1) = 40°C
Wet bulb temperature at the inlet (T2) = 20°C
Wet bulb depression at the exit = 25% of the inlet wet bulb depression
Solution:
Step 1: Calculate the wet bulb depression at the inlet
Wet bulb depression = Dry bulb temperature - Wet bulb temperature
Wet bulb depression at the inlet = 40°C - 20°C = 20°C
Step 2: Calculate the wet bulb depression at the exit
Wet bulb depression at the exit = 25% of 20°C = 0.25 * 20°C = 5°C
Step 3: Calculate the wet bulb temperature at the exit
Wet bulb temperature at the exit = Dry bulb temperature - Wet bulb depression at the exit
Wet bulb temperature at the exit = 40°C - 5°C = 35°C
Step 4: Calculate the dry bulb temperature at the exit
Dry bulb temperature at the exit = Wet bulb temperature at the exit + Wet bulb depression at the exit
Dry bulb temperature at the exit = 35°C + 5°C = 40°C
Therefore, the dry bulb temperature at the exit of the air washer is closest to 40°C, which is option 'C'.
Dry bulb temperature at the inlet (T1) = 40°C
Wet bulb temperature at the inlet (T2) = 20°C
Wet bulb depression at the exit = 25% of the inlet wet bulb depression
Solution:
Step 1: Calculate the wet bulb depression at the inlet
Wet bulb depression = Dry bulb temperature - Wet bulb temperature
Wet bulb depression at the inlet = 40°C - 20°C = 20°C
Step 2: Calculate the wet bulb depression at the exit
Wet bulb depression at the exit = 25% of 20°C = 0.25 * 20°C = 5°C
Step 3: Calculate the wet bulb temperature at the exit
Wet bulb temperature at the exit = Dry bulb temperature - Wet bulb depression at the exit
Wet bulb temperature at the exit = 40°C - 5°C = 35°C
Step 4: Calculate the dry bulb temperature at the exit
Dry bulb temperature at the exit = Wet bulb temperature at the exit + Wet bulb depression at the exit
Dry bulb temperature at the exit = 35°C + 5°C = 40°C
Therefore, the dry bulb temperature at the exit of the air washer is closest to 40°C, which is option 'C'.
