AI Thread Summary
To ensure fluid flows into a vein with a gauge pressure of 18 mm Hg, the IV bag must be hung at a specific height above the vein. The relevant equation relates pressure to fluid depth, which can be used to calculate the required height based on the density of the fluid. Given that the density of the IV fluid is the same as blood, which is 1060 kg/m3, the necessary height can be determined. Understanding the relationship between pressure, depth, and fluid density is crucial for proper IV setup. Accurate placement of the IV bag is essential for effective fluid administration.

An IV is connected to a patient's vein. The blood pressure in the vein has a gauge pressure of 18 mm Hg. At least how far above the vein must the IV bag be hung in order for fluid to flow into the vein? Assume the fluid in the IV has the same density as blood (use 1060 kg/m3 for the density of blood).



I am not sure what equations i should use.

Look for an equation relating pressure to depth in a fluid.
 
ok i got it thanks
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
