  1. Acer computer PC system This is a great example of turbulent flow because when you turn on your computer the pc makes a noise but the question is why. So why does the pc make a noise? It makes the noise because the hot air comes out of the pc when you turn on the computer and the reason the hot air comes out is because there is a fan behind the pc. There is a fan behind the pc because it pushes the heat out of the pc. The heat is in your pc when you use your computer for a long time the pc gets tired so just like all of the humans like us get tired to go to sleep.

  2. A pro dj sound system This is also a good example of the turbulent flow because for these speakers and subwoofers to be loud we need to understand the speakers good quality and the db level meaning the volume level of how loud the speaker/subwoofer can get and the frequency level meaning the level of high frequency (pitch) and low frequency level ( speaker drivers) and how the subs and speakers work to achieve the level of them to getting loud enough. the question is how do these speakers and subwoofers work? Well the answer to that is that the speakers/subwoofers that are built in the cabinets vibrate together in order to give that loudness and base and so these speakers take a lot of air so that’s how they achieve that level. They take a lot of air which is one thing but did you ever think of how much power they take? It is unbelievable for some of you people and DJ’s out there who don’t know much. In my opinion these speakers are 1,000 watts and over so if you have 6 speakers and 2 subs that’s almost at the rate of 8,000 watts imagine how much power that would take. what is the main job that best/good quality DJ speakers have?

  3. What is turbulent flow and laminar flow? We will now continue to get serious of the difference between turbulent flow and laminar flow. As you see in this diagram above it shows the difference by showing lines with arrows which represent the directions of the direction the air goes either going in the direction in straight waves or swirly waves. The straight waves represent the laminar flow and the swirly waves represent the turbulent flow. My proof for how I know this is that laminar flow will always go in straight waves and will not rush and be rough when moving in the air so it will be smooth all the time. So the turbulent flow does not move in straight waves and it is not smooth when moving in the air also it rushes a lot which is why it’s not moving smoothly and it is the reason it is always rough in its form of movement. So this is my information on the difference between turbulent flow and laminar flow.

  4. changing from examples of Turbulent flow to examples of Laminar flow We will now move from turbulent flow to laminar flow. So now at this time I will show you examples of laminar flow.

  5. Example of laminar flow using a DJ speaker cable • Now let’s focus on these SPEAKON speaker wires now it doesn’t have to be DJ speaker cables it can be any wire at all even your printer wires or computer wires or TV cables even microwave cables. Now I will explain why these relate to laminar flow. These relate to laminar flow because the cables and wires are always straight and the flow inside is always smooth and it does not rush through and the main reason that I from my opinion think it is laminar flow is because all the small wires inside of the wire has the same diameter inside of it. So it is not wavy inside it is smooth inside and it flows faster.
