Problem set #7CHE 313 (Spring) __________________ LAST NAME, FIRST Problem set #71-8 Copy the program Mass7.exe from the class distribution folder to your flash or H drive. Youcan also download the program from the website:https://www.csupomona.edu/~tknguyen/che313/homework.htm. Run the program and solve all 8 problems in any order. Solve the problem with the data providedby the program, copy the problem statement to Word. The program will check your answer andprovide an answer code when you click on “Check”. Copy the answer code and paste them afterthe problem statement. Your work should look like this:7) 5Blood is flowing through a hollow fiber based bioartificial organ at a flowrate (Q) of 8cm3/min for each fiber. Surrounding the fibers in the shell space are living cells obtained from apig’s liver. Each fiber has a diameter of 800 microns and a length of 30 cm. At time equal to zero,equal concentrations of a permeable (relative to the fiber wall) test solute and labeled albumin(impermeable) are injected into the blood entering the device. Exiting blood samples arecollected over the next few seconds and analyzed for the concentrations of the test solute (C) andthe reference solute, albumin (Co). (a) At a particular time, the value of C/Co was found to equal0.60. Estimate the permeability (Pm) of the hollow fiber membrane in cm/s. (b) If Pm = 0.018cm/s, determine C/Co.Problem 7: (a) Correct, Code =4313336481(b) Correct, Code =2393636481SolutionThe clearance of a given hollow fiber for the test solute is given byCL = QCo−QCCo = Q(1  C/Co) CL = 8 cm3/min×(1  0.6) = 3.2 cm3/minThe permeability (Pm) of the hollow fiber membrane can be determine from1  oCC = 1  exp(−PmSQ) (a) Pm =  QSlnoCC =  38/60 cm /0.08 cm 30 cmsp � �ln(0.6) = 0.009 cm/s55 Fournier, R.

Idealliquid solutions are expected and we need propane partial pressure (total pressure, P) vs. molfraction of propane in the liquid solution, xp. Write your own Matlab program to plot P vs. xp for atemperature of 200oF. Cover the range 0.1 < xp  0.5.
