Question

30,000 m3 of cool gas (measured at 289 K and 101.3kN/m2 saturated with water vapour) is compressed to 340 kN/m2 pressure, cooled to 289 K and the condensed water is drained off. Subsequently the pressure is reduced to 170 kN/m3 and the gas is distributed at this pressure and 289 K. What is the percentage humidity after this treatment? The vapour pressure of water at 289 K is 1.8kN/m2.
