Find heat removed from air.

Question

20 m³ of air per minute at 30 ⁰C C DBT and 60% RH is sensibly cooled to 22 ⁰C DBT. Take saturation pressure of water vapour at 30 ⁰C and 22 ⁰CV temperatures to be 0.425 bar and 0.0265 bar respectively.

Find heat removed from air.                                                                                              20

Take atmospheric air pressure p_b = 1 bar.
