You should use a benzene-nitrogen psychrometric chart and consider a dry bulb temperature of 38C and an absolute humidity of 0.4kg benzene/ kg dry nitrogen at a total pressure of 1std atm. Estimate: A. the relative humidity, B. the absolute humidity, C. the molal absolute humidity, D. the partial pressure of water, E. the percent humidity, F. the dew point, G. the humid volume, H. the humid heat, I. the enthalpy of saturated air
