Solving Centibarrer Equation - Hg Value & Proper Values

  • Thread starter Thread starter Idea04
  • Start date Start date
AI Thread Summary
The discussion centers on the Centibarrer equation, which calculates gas permeability through a material. Participants clarify that "Hg" refers to centimeters of mercury, indicating pressure, and is crucial for solving the equation. The original poster seeks the correct values to input, specifically for a scenario involving 1 square cm and a thickness of 0.238125 cm over one second. There is uncertainty about the Centibarrer equation itself, with some participants expressing unfamiliarity. Accurate understanding of the pressure difference across the membrane is emphasized as essential for obtaining proper results.

Homework Statement


I have an equation that tells you the number of cubic cm of gas permeable
through an item. But I'm not getting a proper answer.
what does Hg stand for and what is its value. does anyone know the proper values for this equation and how to solve.
the values I have are 1 square cm, .238125 cm thick, time is one second.
I think Hg is to be the partial pressure difference across the membrane.

Homework Equations


10^-8x(cm^2-cm)/cm-Hg-sec-cm^2


The Attempt at a Solution

I've never heard of the centibarrer equation before but cm Hg probably means centimeters of mercury which is a pressure. Hope that helps.
 

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...
