AI Thread Summary
To calculate the height H for the blood container above the patient's arm vein, the pressure equation patm + pgh was applied, resulting in a height of 0.204 meters when considering the vein pressure of 2000 Pa above atmospheric pressure. For draining blood slowly, a lower height is suggested, but the exact value is not provided in the discussion. The density of blood is noted as 1 g/cm^3, which is relevant for pressure calculations. Further clarification is needed for the second part of the question regarding the optimal height for slow drainage. The discussion highlights the importance of understanding pressure dynamics in medical scenarios.

1. Blood travels from a container hanging at a height H abovethe table into the vein of a persons arm. The blood pressure in the vein is 2000 Pa above 1 atm. Blood has a density of 1 g/cm^2

(a) How high should the container of plasma hang above the patient
(b)Suppose you want to drain blood very slowly from the patient into the container. How high should you hang the container in this case.

Homework Equations


3. I used patm +pgh = 1.01X10^5 + 2000 and got H as .204 meters. For b i thought it would be less than .204 meters

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
