Does Pipe Size Affect Water Level Equilibrium in Tanks?

AI Thread Summary
The discussion confirms that the water level in a large tank and a connected pipe will be the same, provided that external pressures are equal. This principle holds true regardless of the pipe size. The relationship is based on the hydrostatic pressure equation, which states that pressure must be equal on both sides to prevent flow. Any difference in water levels would create a pressure differential, leading to water movement. Thus, pipe size does not affect water level equilibrium in this scenario.

Hi

Can someone please confirm me on this one

1. Is this picture correct? (The water level in the big tank and in the pipe will be the same)
2. Water level in big tank and pipe would be the same regardless of pipe size (red)

Thanks

yes, the water level will be equal if the external (air?) pressures are equal.

If this is so, the P= hd of the water must be equal on each side, otherwise there will be a pressure differential between the two sides and that will cause water to flow.
 

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
