fluid Q based on BR physic chapter 7/ passage 3 / Q18 (page 78) and BR gen chem chapter 6 / passage 10 / Q65 (page 42)

both questions ask to find how the height of the fluid in the column changes when one reduces the radius of the column/tube.

the key for both questions explains how the height of the fluid is only dependent on the pressure below the liquid and the pressure above the liquid.. and any changes that do not change the pressure above and below will not change the height of the fluid.

so why is there a change in height for question 65 ( BR's gen chem) and not for question 18 (BR's physics) when there are no changes in pressure for both questions?


thx so much!

thx so much!

Which chapter in the general chem are you talking about? Is it a difference that the system is stationary in general chemistry but flowing in the physics question?

 

[blankmoniker]

this is chapter 6 in the BR gen chem book.

it's my understanding that both systems are nonflowing. or am i misunderstanding the question? :/

thanks again!
