Air is at 1 atm, 40°C, and 20 percent relative humidity. Water at 22°C is evaporated into this air to produce air at 25°C and 80 percent relative humidity. How much water, in kg H2O/kg dry air, is required and how much cooling, in kJ/kg dry air, has been produced? Use data from the tables.
Please help solve the amount
of cooling produced. I believe I am reading the psychrometric chart
incorrectly

Atmospheric air at 32°C and 70% relative humidity passes through a cooling section in an air-conditioning duct where the air is cooled below its dew point and some of the water is removed. The air then passes over a heating section where heat is added until the final temperature is 22°C and the relative humidity is 45%. Assume the process occurs at constant pressure of 1 atm. Using the psychrometric chart, determine: (a) The amount of water removed in the...
Water entering a wet cooling tower at 35°C at a rate of 100 kg/s is cooled to 22°C in the cooling tower by air that enters the tower at 1 atm, 20°C, and 60% relative humidity and leaves saturated at 3...
Water entering a wet cooling tower at 35°C at a rate of 100 kg/s
is cooled to 22°C in the cooling tower by air that enters the tower
at 1 atm, 20°C, and 60% relative humidity and leaves saturated at
30°C. The makeup water of 22°C is supplied to the outlet to make
the mass flow rate of the cool water the same as that at the inlet,
see Figure Q5.

Moist air at 24°C, 1 atm, and 35% relative humidity enters an evaporative cooling unit operating at steady state consisting of a heating section followed by a soaked pad evaporative cooler operating adiabatically. The air passing through the heating section is heated to 45°C. Next, the air passes through a soaked pad exiting with 50% relative humidity. Using data from the psychrometric chart, determine: (a) the humidity ratio of the entering moist air mixture, in kg(vapor) per kg(dry air). (b)...
