Understanding Water Pressure: Solving Homework with P1 and P2 Equations

AI Thread Summary
The discussion focuses on solving a homework problem involving water pressure using the equations P2=P1+pgh. The initial attempt incorrectly suggests plugging in values directly without properly applying the formula. It clarifies that 1.3x10^5 pascals is the pressure in chamber 2, not chamber 1. To find the pressure in chamber 1, users are advised to rearrange the formula for pressure to calculate force using the known area. The conversation emphasizes the importance of correctly applying the given equations to arrive at the right solution.

Homework Equations



P2=P1+pgh

The Attempt at a Solution



I thought you would just plug in the pressure in pascals to p1 and add [(1000 kg/m3)(9.8m/s2)(sqrt 2)]?

Okay find out the pressure in chamber 1. Pressure=force/area.
Did this help?
 
So the answer is just 1.3x10^5 divided by 2?

Why?
 
No, 1.3x10^5 is pressure in chamber 2. Use the forumla given to you in the question to calcualte the pressure in chamber 1. You know the area of chamber 1 and you have calculated the pressure for chamber 1 so rearrange the formula pressure=force/area to give you the force.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
