468 kg/h of sliced fresh potato (78.26% moisture, the balance is solids) is fed to a forced convection dryer. The air used for drying enters at 79°C, 1 atm, and 16.4% relative humidity. The potatoes exit at only 3.09% moisture content. If the exiting air leaves at 90.9% 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.
