Water Pressure, Gauge Pressure, Blood Pressure & Density of Unknown Fluid - Physics Problems

This physics video tutorial explains how to calculate the difference in water pressure between two points, the blood pressure between a person's head and feet, and the density of an unknown fluid given the gauge pressure. This video contains plenty of examples and practice problems.

So you could cause lethal pressure in a bathroom faucet just by installing a slender mile high pipe full of water at the top of the water tank?

will any of these help me figure the amount of pressure water coming out of a container will be? we are going to be placing rain water catchment up about 8 feet and want to know if we attach a water hose to it how fast the water will come out and if we'd be able to water the garden efficiently? thank you!

How can I find out L/s, for a for the 225 dia, (PGH) H=2.0m, P=1000 G=9.81 plz ?

Can I use bernoulli's equation for question 4？

Can I use Bernoulli's equation for question 1?

Hi i have a question
why can't I just find out the height at the level of the heart, and then add the height difference and equate the variables to find the pressure at the level of the head?

What is Hybetez Remedy? Does it work? I hear many individuals treat their high blood pressure issue inherently with this high blood pressure treatment.

[jaepii]

it can be solved also by P=yh, so you don't need to multiply it by 1000 hehe

That's not a cylinder, it's a rectangular prism.

Do anybody know about Hybetez Remedy? Does it work? I hear many individuals cure their high blood pressure issue naturally with this high blood pressure treatment.

These videos are not in order! Please re-arrange your "fluid" videos so I know which order to watch them in.
