A solution containing 0.03 mol/L of sugar in water is fed to a holding tank that initially has 200 L of pure water, in addition to microbes that eat sugar. The sugar disappears
at a rate (r= 0.055cs) proportional to its own concentration (ܿcs). The volumetric feed to the tank is increased linearly from 0 to 35 liters per second over a ten‐second period, and
remains constant thereafter at 35 L/s until the tank isfilled to a desired level.
(a) What are the values for the sugar concentration in the tank and the total volume of liquid in the tank after a 60‐second period of time?
(b) Create a pair of plots (or a single unified plot) showing the tank volume and sugar concentration in the tank over the span of 0 to 60 seconds. You may use the plotting
method of your choice!
(c) Display the entire program code used for your problem solution in Polymath.
(c) This part can be solved by pasting above solution in polymath software with the help of ODE equation and putting initial guess value as given in solution as follows:
dV/dt=V1
V1(0)=0
V(0)=200
dCs/dt=((V1/V)*Cs1-(0.055*Cs))
Cs1=0.03
V1(0)=0
Then select graph and table, click the green triangle to run or draw the graph.
