662 kg/h of sliced fresh potato (72.55% moisture, the balance is solids) is fed to a forced convection dryer. The air used for drying enters at 68oC, 1 atm, and 16.4% relative humidity. The potatoes exit at only 2.38% moisture content. If the exiting air leaves at 88.8% humidity at the same inlet temperature and pressure, what is the mass ratio of air fed to potatoes fed? Type your answer in 3 decimal place
