329 kg/h of sliced fresh potato (70.64% moisture, the balance is solids) is fed to a forced convection dryer. The air used for drying enters at 60°C, 1 atm, and 15.7% relative humidity. The potatoes exit at only 3.39% moisture content. If the exiting air leaves at 91.0% humidity at the same inlet temperature and pressure, what is the mass flow rate of the outlet air? Type your answer as a whole number rounded off to the units digit.
