An air-conditioning system operates at a total pressure of 1 atm and consists of a heating section and an evaporative cooler. Air enters the heating section at 15°C and 55 percent relative humidity at a rate of 30 m3/min, and it leaves the evaporative cooler at 25°C and 45 percent relatively humidity. Using appropriate software, study the effect of total pressure in the range 94 to 100 kPa and plot the results as functions of total pressure.
