Dear all,
I wrote the code below now, I have initial concentration 6mg/L but i need to calculate when it reaches (0.05*6) mg/L. Could you help me please? I need the t value when concentration is equal to (0.05*6) mg/L
Z0=6;tspan = [0 24]; [tZ,Z] = ode45(@ConcDCE,tspan,Z0); function dZdt=ConcDCE(t,Z)k1=1.26;k2=0.74;k3=0.22;X0=1;Y0=4;Z0=6;dZdt=k2*(Y0*exp(-k2*t)+((X0*k1)/(k2-k1)*(exp(-k1*t)-exp(-k2*t))))-k3*(Z0*exp(-k3*t)+((Y0*k2)/(k3-k2)*(exp(-k2*t)-exp(-k3*t)))+X0*k1*k2*((exp(-k1*t))/((k2-k1)*(k3-k1))-(exp(-k2*t))/((k2-k1)*(k3-k2))+(exp(-k3*t))/((k3-k1)*(k3-k2)))); end
