Fluids -- pressure Blood plasma flows from a bag through a tube into a patient's vein, where the blood pressure is 10 mmHg. The specific gravity of blood plasma at 37°C is 1.03. What is the minimum elevation the bag must have so the plasma flows into the vein? Prof gave this problem for us to solve, and I went through my notes and didn't see much that would help me get started. I got this equation P = P0 + density * g * h density = mass / volume Is this equation relevant to this problem? Im given the pressure 10 mmHg, gravity 1.03, but what is the density? I need to solve for height. Can someone help me get started?
