Syphons seem almost like magic. They move liquids from high to low points without any mechanism other than a tube. In this video we will be going over how syphons work, how to calculate the average velocity of a syphon and what the siphons limitations are.
Syphons consist of a hose or pipe that is filled with water with one end in a liquid resvoir and the other end lower than the water line in that resvoir.
So the way the syphon works is first the hydrostatic pressure on the end with more liquid causes the liquid to have a higher velocity on that end.
This causes a reduced pressure at the top of the syphon. You can think in terms of the manometer problems we previously completed.
Water than flows upward due to the low pressure. The water is being pushed up by the atmospheric pressure. The pressure at the top of the tube is lower than atmospheric pressure.
Now lets use our friend the bernouilli equation to solve this problem. We can eliminate the pressure because atmospheric pressure is affecting both ends of the syphon. In order to solve this problem we need to think back to how potential and kinetic energy works. (see car going up and down hills video) Being there is a hight decrease we can convert potential energy at one end into kinetic energy at the other. This means that we can set potential energy equal to kinetic energy. So lets begin rearranging the formula.
We notice that density is on both sides so it can be canceled out.
We that multiply times 2 and take the square root of the potential energy side now we have our formula.
We now must plug in the height. I used the height difference between the 2 glasses when half filled. This is .133 meters. This works because we are trying to find the average velocity.
After we plug in all of our numbers we get that the velocity on average is about 1.62 meters per second. This is about 5.8 kilometers per hour or about 3.6 mph.
The limiting factor of a syphon is the pressure at point c. If the pressure ever decreases to boiling point of the fluid cavitation happens and the stream will be broken. This limits the height and velocity of a syphon. Another limit of the syphon is that the water always flows from higher to lower elevation.

Deep Space. Incredible Objects of the Universe | ReYOUniverse


People have always tried to comprehend the world around them. Today we learn about the world not only on Earth, but also far beyond. Beyond the solar system and even our galaxy. Thanks to this, we’ve discovered countless celestial bodies, for surely our universe has all kinds of cosmic objects. So let’s take a trip to see the most unusual ones. We’ll begin our journey with the largest void in the universe. It is so huge that time inside it seems to stop. Next, we are going to visit the stars inside our galaxy whose very existence seems implausible. They keep everyone puzzled and leave us with more questions than answers. Next, we’ll take a trip beyond the Milky Way to see zombie galaxies. Do you want to find out what it is? Two of the stops will be deadly magnetars that can extract iron from a person’s blood, being thousands of kilometers away, and black holes, whose very existence is frightening.
This is a documentary about space the spectacular space objects of the universe.

Today we are talking about motion, specifically speed, velocity, and acceleration.
Let’s clear a few things up right off the bat. Speed and velocity ARE different. And acceleration is much more than “speeding up”
Speed is the rate at which something changes position. It’s represented as distance over time. M/h, Km/h, and m/s are examples of units for speed. If you’re driving 72 mph in your car, then that is your speed, in fact, it’s your instantaneous speed, which is the speed you are traveling at that exact moment. If you get to the end of your trip and discover it took you 2 hours to go 120 miles, you overall speed was 60 mph. This is your average speed.
Velocity is a lot like speed except for one important difference, it is a vector, meaning it has a direction. So while your speed may have been 72 mph, your velocity was 72 mph east, or 72 mph toward the ocean. There just has to be some direction attached to the speed to make it a velocity.
With that knowledge in hand you can now understand acceleration, which is simply the rate at which velocity changes. It’s units are distance per time per time, or distance per time squared. m/s2 for example. Any time you change velocity you are accelerating. This includes speeding up and slowing down (which is called negative acceleration). But direction is also a component of velocity, so when you change direction you are accelerating, even if your speed does not change. Does that blow your mind?
Alright, let’s recap. Speed is the rate at which something moves, distance over time. Velocity is speed with a direction, so distance over time with a specific direction. And acceleration, the king of them all, is distance over time squared, aka the rate at which velocity changes. Whether you are speeding up, slowing down, or changing directions, you are changing your velocity and thus, accelerating.
