Question

The compressed air compressor absorbs air at 101.3 kPa, 10 ° C and relative humidity
60%. After the compressor, the compressed air temperature is 30 ° C and the pressure is 300 kPa. What is the relative humidity of the compressed air produced?

Answer 1

As far as humidity γ₂  = n₂/n_l2  i.e.  γ₂ = p₂/p_l2 = p₁(p_t2/p_t1)/p_l2 = γ₁(p_l1/p_l2) (p_t2/p_t1) = 0.6(1.23/4.21)(300/101.3) = 0.52 or 52%.
