//INPUT
u_oa_by_u0=0.88;//Refer equation 3.64
u_ob_by_u0=1.12;
X_A=0.95;//Conversion
L=2.5;//(ft)
L_a=3;//Length of section a (ft)
L_b=2;//Length of section b (ft)

//CALCULATION
k_rho_L_by_u=log(1/(1-X_A));//First Order reaction
//For Section a
k_rho_L_by_u_a=k_rho_L_by_u*(L_a/L)*(1/u_oa_by_u0);

delP_a_by_alpha_u0_pow=L_a*(u_oa_by_u0);//Refer equation 3.64

//For Section b
k_rho_L_by_u_b=k_rho_L_by_u*(L_b/L)*(1/u_ob_by_u0);//Dimensionless Group based on ideal plug flow for first order reaction
delP_b_by_alpha_u0_pow=L_b*u_ob_by_u0;
