Expert Solution & Answer
Check Mark
To determine

The reason of dripping of water from air conditioning unit.

Answer to Problem 34A

Due to condensation the water comes from air condition unit on hot day.

Explanation of Solution

When the dry hot air strike with evaporating coils condensation take place and this converts into droplets & water come from the air condition unit .

Conclusion:

Due to condensation the water comes from air condition unit on hot day.
