On a hot summer day at Tallahassee, FL, the temperature of the outside air is 35oC and the pressure is 103kPa. The relative humidity is 90%. An air conditioner draws in outside air, cools it to 20oC, and delivers it at a rate of 528.5 mol/h. Calculate the rate of moisture condensation (mol/h) and the volumetric flow rate of the air drawn from the outside.

Earth's climate extremes are moderated by circulation patterns in the oceans and the atmosphere that move heat from the tropics pole wards. Warm tropical waters evaporate and are moved by currents in the upper atmosphere to mid-latitudes where the water vapor cools, condenses, and falls as rain. a) How much heat energy is released to the upper atmosphere in the mid-latitudes when a vaporous mass of .034g of water condenses into a raindrop? b) After it forms, the temperature of the raindrop falls another 13C. How much more energy is released to the atmosphere in this process? The latent heat of fusion for water is 33.5*104 J/kg The latent heat of vaporization of water is 22.6 *105 J/kg The specific heat of water is 4186 J/(kgC)

1.14 Two pounds of water vapor at 30 psia fill the 4-ft' left chamber of a partitioned system. The right chamber has twice the volume of the left and is initially evacuated. Determine the pressure of the water after the partition has been removed and enough heat has been transferred so that the temperature of the water is 40°F.
