A gas mixture with 20% Neon with pressure 3 atm at 27^oC is entered a reactor with rate F, and another stream with pure Neon with 2 atm pressure at 27^oC entered the reactor with rate 5 liter/s, product has 40% Neon with same conditions with rate P, what is the value of F?(a) 3 liter/s(b) 15 liter/s(c) 30 liter/s(d) 45 liter/sThe question was posed to me by my college director while I was bunking the class.I'd like to ask this question from Material Balances Involving Ideal Gases in chapter Recycle, Bypass, Purge, Ideal Gases and Real Gases of Basic Chemical Engineering

Answer»

The CORRECT option is (c) 30 liter/s

The explanation: Neon balance- 0.2*F*3 + 5*2*1 = 0.4*P*2, => 0.6F + 10 = 0.8P, OVERALL balance- F + 5 = P, => F = 30 liter/s.
