Step 1: By using psychrometric chart, take a look at horizontal axis to find 45°C.
Step 2: Move a pencil up this line to meet the intersection with the exponential line 40% relative humidity.
Step 3: Identify the dew point which is 35°C. From this evaporator coil is warmer than the dew point so it will condense water from air.
