1. The problem statement, all variables and given/known data

The osmotic pressure (π) of the blood plasma necessary to induce absorption of water from interstitium (outside) to the capillary bed under circumstances shown on the picture (attached) has to be
a. Less than 20 mmHg
b. Between -1 and 20 mmHg
c. Equal to 21 mmHg
d. Greater than 21 mmHg


2. Relevant equations

see below

3. The attempt at a solution

I'm guessing the correct answer is (c) equal to 21.
Something like (20+1)-(?-0).... Am I on the right track, or completely wrong?
