Question

clear answer please.

Problem 1:

What is the upper limit on how far chocolate milk (density = 1.04 g/cm3) can be sucked through a vertical straw, assuming you can obtain a perfect vacuum with your mouth? Explain any assumptions

Problem 2:

Blood pressure is related to the force of blood pushing against the walls of your arteries as your heart pumps. Really high blood pressure is 160 mm Hg (gage pressure). What is the minimum length of a vertical tube open to the atmosphere and connected to a vein of a person with really high blood pressure needed to accommodate the rise of fluid within the tube? Use a rblood = 1.02 g cm-3

Explanation / Answer

1. Let maximum height be h.

                Then, density*g*h= atmospheric pressure

                                1040*9.8*h=101325

                                h=9.935 m

2. Height of blood/Pressure in mm Hg=rHg/rblood

                Length of tube=height of blood risen

                                                =(13.6/1.02)*160

                                                =2133.3 mm
