Air Coolers Evaporative Cooling

Chemistry will !!!!!!!!!!!!!!!?

n regions with dry climate, coolers are evaporative cooling can be used to force air . Cool A typical electrical air conditioning system is rated at 104 BTU 1.17 per hour (1 Btu or British Thermal Unit is the amount of energy to the temperature of 1 pound of water by to increase 1 ° F). How much water to disperse hour each must be evaporated as much heat as a typical electrical air conditioning? ___kg / hr

♥ ♥ Hi, Strange, did not they give the temperature of the system and thus the water. In fact, the evaporation is temperature dependent. Let us assume that they mean the system at 298.15 K. The vaporization of water is given in several articles K. than 44.0 kJ / mol at 298.15 ° Since there are 4.184 J / cal, AH (VAP) = 44.0 kJ / mol / (4.184 kJ / kcal) = 10.5 kcal / mol. AH (VAP) = 10.5 kcal / mol / (18.015 g / mol) = 0.583 kcal / g Note that a calorie is the amount of a Energy required to raise one gram of water ° C. That is, it would take 453.59 cal / lb raise it 1 ° C, and thus (since 1 ° C = 1.8 ° F), 252 ° F cal/lb- Therefore BTU = 252 cal replaced by electric heating heat 1 x = 1.17 x 10 ^ 4 BTU / hr x 252 cal / BTU = 2.95 x 10 ^ 6 cal / h = 2.95 10 ^ 3 kcal / h of water evaporated per hour = 2.95 x 10 ^ 3 kcal / h / (0.583 kcal / g * 1000 g / kg) = 5,06 kg / h Hope That helped!
