(Solved) : Use Runge Kutta Method Matlab Solve Following Problem 120 Tubular Reactor Homogeneous Reac Q42700300 . . .

Use Runge kutta method in matlab to solve the following problem 120. A tubular reactor for a homogeneous reaction has the following dimensions: L = 2 m, R = 0.1 m. The inlet reactant concentration is cho = 0.03 kmol/m3, and the inlet temperature is T. = 700 K. Other data are as follows: -AH = 104 kJ/kmol, Cp = 1 kJ/(kg K), Ea = 100 kJ/kmol, P = 1.2 kg/m>, u. = 3 m/s and ko = 5 sec-1. The material and energy balances for this reactor result in the following two differential equations after normalization. dy/dz = -Da y exp [8 (1 – 1/0)] de/dz = B Da y exp [8 (1 – 1/0)] – Hw (0 – 0) z = x/L y = c/c. = T/T 0 < z y (z=0) (z=0) < = = 1 1 1 Ow= Tw/T. Da= Lko/uo 8 = Ea/RgT. B = co(-AH) /popt Hv= 2h/R (L/PCpu) = 1. = 3.333 = 0.0172 = 0.357 = 0. a) solve this system of equations if the convective heat transfer coefficient, h, is 0. b) Now assume the overall heat transfer coefficient between the wall and the reactor contents is h= 70 J/(m2 s K) and the wall temperature of the reactor Tw = 700 K. This makes Hy= 2h/R (L/pcpu) = 0.778. Solve this system of equations to determine the outlet reactant concentration and to find the location of the hottest temperature on the reactor wall.
