If you really have the need for speed, you'll want to achieve maximum aerodynamics. The smaller and more streamlined you're able to manipulate your body shape, the faster you'll move. So, what's the ideal position for going down a residential water slide? We recommend crossing your arms and legs as you lay back.
Why do drops of water slide down a smooth surface faster than drops of oil?
Why do drops of water slide down a smooth surface faster than drops of oil? Because of viscosity. Water is very different from oil. It pours easily, and it is not thick and sticky like oil.It is more dense than oil.
Does oil flow faster than water True or false?
Oil has more stickiness than water. It sticks to the surface on which it is flowing. Hence, it takes more time to flow.
Which drops slid down slowest why?
Oil drop slides slower because of its stickiness. As sugar water is more sticky than normal water, it slides slower than the water drop.
Do heavier people go down waterslides faster?
He explains that heavier riders won't go much faster than the speed of the water itself. "They can't break through the deep water," he says. "But a lighter rider—that person will get flushed and get swept up by the water and they'll eventually reach the speed of the water."
What makes a slide go faster?
Different things affect how fast you move down a slide. The surface of the slide, the clothes you are wearing, how heavy you are, and the amount of your body touching the slide all make a difference. Whether the slide is flat, wavy, or spiral makes a difference too.
Why is it easier to slide in a smooth surface than rough surface?
A rough surface will have more friction because on the rough surface there will be more irregularities. They will cause interlocking which in turn creates more frictional force. For a smooth surface, irregularities and interlocking is less and hence has very less friction.
Why does water make you go down a slide faster than without water?
Water reduces friction on the water slides. Hence, we move faster on water slides as there is less friction.
Which fluid flows faster?
Water flows faster than other liquids because it has a lower viscosity. Viscosity is a measure of a liquid's resistance to flow. Liquids with high viscosity, like molasses or honey, are thicker and more resistant to flow, while liquids with low viscosity, like water or gasoline, are thinner and flow more easily.
Does water flow faster at the top or bottom?
The slowest moving water is next to the bottom and each successive layer of water toward the surface flows faster than the layer below it. The fastest moving water is found just below the surface. This is because the air next to the surface creates friction which slows the surface water slightly.
Which drops slide down faster?
Which liquid will flow slowest when poured?
Liquids that have a HIGH viscosity flow slowly (ie. honey, corn syrup, and molasses). Viscosity can also be thought of as a measure of how “thick” a liquid is. The more viscous (or thick) a liquid is, the longer it will take for an object to move through the liquid.
Why does oil flow slower than water?
Oil is less dense than water (it floats on top of water) but more viscous than water. Oil resists flowing, where water flows more easily. Pitch is so viscous that, in a 91 year experiment that is still happening, a small quantity hasn't finished flowing out of a funnel and into a glass!
Why do bigger people go down slides faster?
So if bigger people go down the slide faster, their weight which is greater exceeds the resistance force by a greater margin. Net force = (weight – resistance) = mass x net acceleration is greater. If they go down faster, their net acceleration is greater.
Does weight affect how fast you fall?
The acceleration of the object equals the gravitational acceleration. The mass, size, and shape of the object are not a factor in describing the motion of the object. So all objects, regardless of size or shape or weight, free fall with the same acceleration.
Why do some people go down slides faster?
Acceleration due to gravity at sea level is 9.81 ms-2. This ignores air resistance. So in free fall without air resistance at sea level the acceleration for any mass is the same. So if bigger people go down the slide faster, their weight which is greater exceeds the resistance force by a greater margin.
How do you make a slip and slide go faster?
Ensuring there is enough water on the slide at all times is essential to getting ample acceleration and avoiding friction burns. Having a main water source at the top that runs to the bottom as well as sprinkles of water along the way makes for a slippery, cool, and fun slide.
Is smooth or rough better for friction?
A rough surface will have more friction because on the rough surface there will be more irregularities. They will cause interlocking which in turn creates more frictional force. For a smooth surface, irregularities and interlocking is less and hence has very less friction. Q.
Do different surfaces affect the amount of slide?
The item with the least friction will start to slide first. There are two main factors that will influence the total amount of friction: 1) the roughness of the surfaces (or the "coefficient of friction") and 2) the force between the two objects.
What makes a slide fast?
Different things affect how fast you move down a slide. The surface of the slide, the clothes you are wearing, how heavy you are, and the amount of your body touching the slide all make a difference. Whether the slide is flat, wavy, or spiral makes a difference too.
What are the 3 types of fluid flow?
There are three fluid flow regimes: laminar, turbulent, and a transition region. The conditions that lead to each type of flow behavior are system-specific. Fluid flow simulations for various Reynolds numbers can be used to clearly identify and quantify when flow will transition from laminar to turbulent.
