A modified atmosphere requires higher-than-normal amounts of oxygen but sparing amounts of water vapor. You have two streams available for mixing. • stream A is dry air (79% N2, 21% O2) • stream B is enriched air saturated with water vapor (4.22% water vapor, 56.94% O2, and the balance is N₂) The desired product should contain 0.89% water vapor. Determine the product to enriched air ratio (P/B) that satisfies the given composition required. Type your answer in 2 decimal places. 4

Question
A modified atmosphere requires higher-than-normal amounts of oxygen but sparing amounts of water vapor. You have two streams available for mixing:
• stream A is dry air (79% N2, 21% O2)
• stream B is enriched air saturated with water vapor (4.22% water vapor, 56.94% O2, and the balance is N2)
The desired product should contain 0.89% water vapor. Determine the product to enriched air ratio (P/B) that satisfies the given composition required.
Type your answer in 2 decimal places.
