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 m5/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.
