Question
Transcribed Image Text:3.13 Heparin is a common anti-coagulant. To prepare an IV containing heparin and buffers, you acquire a
large mixing tank. For this problem, assume a simplified system in which there are three inlet streams and
one outlet stream. In mixing the solution, you keep track of two constituents: heparin and bicarbonate.
Streams 1, 2, and 3 enter the mixer; stream 4 leaves the mixer. Stream 1 contains 300 mM heparin in water.
Stream 2 contains 200 mM bicarbonate in water. Stream 3 contains water with no heparin or bicarbonate. The
overall mass flow rate in Stream 4 is 1000 g/min. The outlet stream contains 60 mM heparin, 30 mM
bicarbonate, and water. Assume that the density of every stream is 1.0 g/cm³.
a. Determine the flow rate (in g/min) of streams 1 and 2 such that the desired heparin and bicarbonate
compositions are met.
b. Determine the total mass flow rate (in g/min) of stream 3.
Expert Solution
Step 1
Given that
Stream 1 contains 300 mM heparin in water.
Stream 2 contains 200 mM bicarbonate in water.
Stream 3 contains water with no heparin or bicarbonate.
For outlet stream, mass flow rate =1000 g/min. and it contains 60 mM heparin, 30 mM bicarbonate, and water.
density =1.0 g/cm3 = 1 g/ml
