A mixture of dry air and water vapour, when the air has diffused the maximum amount of water vapour into it, is called
The temperature of air recorded by a thermometer, when it is not affected by the moisture present in it, is called
The wet bulb depression is zero, when relative humidity is equal to
Web bulb depression is the difference between DBT and WBT at any point. It indicates relative humidity of air
The relative humidity of air is defined as the ratio of
The minimum temperature to which moist air can be cooled under ideal conditions in a spray washer is
The by-pass factor of a cooling coil decreases with
The BPF depends upon the following factors:
1. The number of fins provided in a unit length i.e. the pitch of the cooling coil fins.
2. The number of rows in a coil in the direction of flow.
3. The velocity of flow of air.
The process generally used in winter air conditioning to warm and humidify the air, is called . .
In order to cool and dehumidify a stream of moist air, it must be passed over the coil at a temperature
The moisture content of air is indicated by
