2. (3 pt) Heat Transfer from Tubular Reactor (Problem 8 from Midterm #1) Hint: Read through ALL SUBPARTS of this problem, before starting. Consider a tubular reactor for which the wall is a cylindrical glass shell of inside radius r₁= 1.0 cm and outside radius r2 = 2.0 cm, and length L = 0.5 m. Inside the tube core (inside r₁) is a reaction mixture of uniform temperature 7; = 60 °C, which generates q = 5 x 10^5 W/m³ heat due to exothermic reaction.
