Q.3 Saturated ambient air with a db-temperature of 5°C and a mass flow rate of 0.9 kg/s is divided
into two streams. One stream passes through a heating section and leaves it with a relative humidity
of 25%. The conditions of the other stream that bypasses the heater remains unchanged. The two
streams are then mixed to produce the supply air stream at 24°C. The pressure is constant
at 101.3 kPa. Determine (i) heat input by the heating coil, and (ii) the mass flow of air
through the bypass section.

Expert Solution

Step 1

The ratio of the current absolute humidity to the highest attainable absolute humidity is known as relative humidity (which depends on the current air temperature). The dry bulb temperature of air, often known as DBT, is the temperature of the air measured by an ordinary thermometer. When a regular thermometer is exposed to the air, it reads the dry bulb temperature, which is the same as the ambient temperature. A factor known as the by-pass factor (BPF) or Coil Bypass Factor indicates a coil's incapacity to cool or heat the air to its desired temperature.
