a-) Since the dew point temperature of the air entering a dryer is 35°C and the % humidity value is Hp=30%; find the properties of the air (T, H, T, H) using the humidity chart. b-) Find the saturation humidity and saturation temperature of the air-water vapor mixture with a wet bulb temperature of 40°C and a dry bulb temperature of 80°C. (H, T) c-) The air-water vapor mixture with a dry bulb temperature of 65°C and a moisture content of H-0.03 (kg H2O/kg dry air) enters an adiabatic saturator and leaves the saturator at 70% saturation. Find the characteristics of the air at the Saturator Outlet using the humidity chart. d-) The dry bulb temperature of the air entering an adiabatic saturator is 50°C and its % moisture content is Hp=30%. If the temperature of the air at the exit of the saturator is 42.5°C, what is the saturation %? urgent please
