2. Humid air at 35C and a pressure of 1 atm and with 98% relative humidity enters a condenser in which the temperature is lowered isobarically (pressure is constant) to 15C. Part of the water condenses and coexists with the remaining air. The remaining air leaves the condenser flowing through a 20-cm diameter duct at a velocity of 10 m/s. Calculate the rate (moles water/s) at which water condenses
