Problem:

You are collecting plasma from a patient with a pheresis machine that takes wholeblood from the body, extracts 80% by mass of the plasma and returns the remainderof the blood to the body. For this operation the blood composition can be modeledas 55% by mass plasma and 45% by mass cells. If a patient donates 1.0 liter of plasma (density=1025 kg/m3),

calculate the following:

Question 1: The amount (mass) of blood extracted from the donor. (ANS: 2329 g)

Question 2: The concentration (mass fraction) of cells and plasma in the concentrated blood.(ANS: xc=0.804 g cells/g)

Question 3: The mass of concentrated blood returned to the donor. (ANS: 1304 g)

Show the pedigree and your calculation.
