The pressure on a fluid at rest in a pipe increases by 20 Pa. How does this change in pressure affect the pressure on the fluid in the rest of the pipe?
1. The pressure in the rest of the fluid stays the same because the pressure only increased in one area and that does not affect the rest of the fluid.
2. The pressure on all the fluid in the pipes increases by up to 20 Pa because pressure will increase on all the fluid but by different amounts.
3. The pressure on all the fluid in the pipes increases by more than 20 Pa because the amount of pressure adds up on the rest of the fluid in the pipes.
4. The pressure on all the fluid in the pipes increases by 20 Pa because fluid pressure is transmitted undiminished to all points in the fluid
I believe the answer is 2. Is this correct?
The answer is 4. The pressure on all the fluid in the pipes increases by 20 Pa because fluid pressure is transmitted undiminished to all points in the fluid.
Pascal's Principle mentions that all the pressure is evenly distributed throughout an object/container
hope this helps!! <3
