3. Use the given Psychrometric chart to determine the following psychrometric of a.015 of dty air. The total pressure is and the vapour pressure bar Where is in . Relative humidity b) Relative c) Wet bulb temperature d) Enthalpy e) Humid volume
Expert Answer
there for the first part is =a) Relative humidity:From the information given, we know the dry bulb temperature and the vapor pressure of water at that temperature. We can calculate the saturation vapor pressure at the dry bulb temperature using the Antoine equation for water:log10(P) = A - (B / (T + C))where P is the saturation vapor pressure in bar, T is the temperature in K, and A, B, and C are constants. For water, the constants are:
