On a hot summer day the temperature is 35°c, barometric pressure is 103 kpa, and the relative humidity is 90%. an air conditioner draws in outside air, cools it to 20°c, and delivers it at a rate of 12,500 l/h. calculate the rate of moisture condensation (kg/h) and the volumetric flow rate of the air drawn from the outside.

the correct answer to this question is 2

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
