Determine the dry and wet bulb temperatures of leaving air.

Question

Moist air enter a chamber at 5⁰C DBT and 2.5⁰C WBT at a rate of 90 m³/min. The barometric pressure is 1.01325 bar. While pasing through the chamber, the air absorbs sensible heat at the rate of 40.7 kW and picks up 40 kg/hr of saturated steam at 110⁰C. Determine the dry and wet bulb temperatures of leaving air.

Properties of steam are given below :

Enthlapy of saturated steam at 110⁰C is 2691.3 kJ/kg.
