energy efficiency in buildings calculation please re do the table and write down the detail

Exercise 2: Space conditionning Part 1: Moist air properties Place the points given by two of their characteristics on the psychometric charts and complete the following table on your sheet by taking the values on the diagram. It is necessary to note and place the points on the diagram precisely (see annex page 7) Point A Point B Point Point D Point E 20 25 30 13 8 50 Characteristics Dry temperature (C) Wet temperature (C) Relative humidity RH (%) Humidity ratio W (Kgw/Kgda) Specific volume (m/Kg) Enthalpy (kJ/kg) Vapor pressure (Pa) Dew point temperature (C) 0.004 0.85 42 15 Saturation Humidity ratio Ws (Kgw/Kgda) Part 2: Mixing air stream The mixture of 2 moist airs has the following characteristics: - Point A (Td = 20 C and Tw= 13C) with a flow rate of 5000 m3/h - Point (Tw=8 C and W = 0.004 Kg/Kg) with a volume flow of 3500 m3/h 1) Determine the mass flow rates of dry air (qmda) for air, (point A) and for airz (point C)? 2) Determine the characteristics of the mixture (TM, WM, hm and HRM) by using psychometric chart
