Question

On the psychrometric chart provided mark clearly the point for air with a
dry bulb temperature of 30oC and a Percentage Saturation of 80%.
At this air condition, by referring to the same chart, what are the values of
wet bulb temperature, specific volume, moisture content in kg/kg (dry air)
and enthalpy.

If the air is air-conditioned to 15oC dry bulb and a Percentage Saturation of
60, what is the associated enthalpy drop.
