In a plant for the recovery of acetone which has been used as a solvent, the acetone is evaporated into a stream of nitrogen gas. A mixture of acetone vapor and nitrogen flows through a duct, 0.3 by 0.3m cross section. The pressure and temperature at one point in the duct are 740mmHg and 22C while average mixture velocity is 3.0m/s. A wet bulb thermometer (wick wet with acetone) indicates a temperature at this point of 18C. Calculate: A. the hG/kY ratio, B. the absolute humidity, kg acetone/kg dry nitrogen, C. the mixture flowrate, m3/s, D. the humid volume, m3 mixture/ kg dry nitrogen, E. the dry nitrogen mass flowrate, kg dry nitrogen/s, F. the acetone mass flowrate, kg acetone /s
