Air, dry bulb temperature 40 ¡ÆC, wet bulb temperature 27¡ÆC, is scrubbed with water which is maintained at 24 ¡ÆC . Assume that equilibrium is reached between air and water. The air is then heated to 60 ¡ÆC by passing over steam coils. It is then used in an adiabatic rotary drier from which it issues at 45 ¡ÆC
What is the humidity of air (i) initially; (ii) leaving the scrubber; (iii) after reheating; (iv) leaving the drier?
