Solving for Blood Pressure Difference: What Now?

AI Thread Summary
The discussion focuses on calculating the difference in blood pressure between the top of the head and the bottom of the feet for a 1.60-meter tall person. The formula used is Δp = pgh, where p represents the density of blood, g is the acceleration due to gravity, and h is the height difference. The user expresses frustration over a lack of values provided in their textbook, particularly the density of blood (p). They attempt to use known values for g and h but are confused about how to proceed without the density. The conversation emphasizes the complexity of blood pressure dynamics, which are influenced by factors beyond just gravity.

Homework Statement



I don't know why everybody ignore my urgent questions.
I do not know what to do seriously.

What is the difference in blood pressure (mm-Hg) between the top of the head and bottom of the feet of a 1.60-m-tall person standing vertically?

I know △p = pgh but in this book, they do not gives to any values.

I want to know how it works if I don't know p



Homework Equations



△p = pgh

The Attempt at a Solution



I know the gh values so... △p = p(9.8m/s^2)(1.60m)

but, I don't know what the hell is this.

Blood pressure in the human body not only depends on the gravity as is is a dynamic fluid which is constantly compressed by the heart beats.

If rho is not given then express your answer as a percentage of rho.

Thread 'Errors and significant figures'

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'

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...
