Moment of Inertia of a Liquid in a Cylinder Exploration: Intro One night, out babysitting, I found myself playing with a toy garage, making little cars go down the ramp. You place the little car at the top floor of the toy garage and watch it go down. Some cars zoom down, others got stuck, others toppled over and flew off the track. This made me think of those heavy trucks filled with liquid and how they behave in a crash. Bulk liquid transport trucks when that are only partially filled are especially dangerous as the liquid can move around from side to side inside the liquid container and make the ‘load’ unsafe in a crash situation and cause the truck to roll over. I wondered if the viscosity of the load increased or decreased this danger? Moreover, would it …show more content…
However, with a variation of liquids with various viscosities and the mixed phase of liquid and gas -, the content of the cylinder may not move with the cylinder at the same rate. With the can containing a mixed phase of liquid/gas, the moment of inertia I is therefore not fixed. The liquid in the can move around and since I=∫▒r2dm Depending on distance I will change. In addition, the viscosity of the liquid will change the behavior of the contents even further because you will not only have a mixed phase of liquid/gas but also different viscosities in other words different measures of the fluid’s resistance. Viscous forces in a fluid are proportional to the rate at which the fluid velocity changes in space. The viscosity thus changes the liquids ease of moving around inside the cylinder. The higher the viscosity, the slower are the fluctuations in
It was learned that changing the volume of the same substance will never change the boiling point of the substance. However having two different substances with the same volume will result in two different boiling points. The purpose of this lab was to determine if changing the volume of a substance will change the boiling point. This is useful to know in real life because if someone wanted to boil water to make pasta and did not know how much water to
Olefin/paraffin separation is very difficult to achieve because the molecules are similar in size and volatility. The relative volatility of propylene and propane mixture is 1.1 and that of ethylene and ethane is 1.5. Traditional
(CNG). That's because the gas is confined to a pressure of approximately 3,600 pounds p...
Label a 25 mL graduated cylinder ”A”. Fill it to the 25.0 mL mark with water. This is the REACTANTS. Label a second 25 mL graduated cylinder ”B”. This is the PRODUCTS. This cylinder will begin empty. Why is it empty at this stage?
heat will stay in the cup and can only escape by rising to the surface
The website https://en.wikipedia.org says that liquids are one of the four primary states of matter. On https://en.wikipedia.org, it also states, “A liquid is a fluid. Unlike a solid, the molecules in a liquid have a much greater freedom to move. The forces that bind the molecules together in a solid are only temporary in a liquid, allowing a liquid to flow while a solid remains rigid.A liquid, like a gas, displays the properties of a fluid. A liquid can flow, assume the shape of a container, and, if placed in a sealed container, will distribute applied pressure evenly to every surface in the container. If you place the liquid in a bag, you can squeeze it into any shape you want. Unlike a gas, a liquid may not always mix readily with another liquid, will not always fill every space in the container, forming its own surface, and will not compress significantly, except under extremely high pressures. ” Liquids also don’t have its own shape so it takes the shape of its container. There are all kinds of liquids all around you. Some examples are water, milk, oil, and
The fluid is assumed to be incompressible that when pressure changes, the density of the fluid remains constant.
The performance curves based on the ethylene glycol solution will be compared to those developed using water as the base to examine the effect, if any, the viscosity and density of the liquid has on the pump.
On that fateful day in March, I was a couple months shy of my third birthday. My family and I lived in New Mexico at the time and were renting a house with an outdoor in-ground pool. The day was beautiful. I was outside with my oldest sister Rachel and my father. Rachel was diligently reading curled up on a bench that sat against the house, and my father was mowing the backyard. My mother and my other sister were in the house. Off to one side of the house there was a group of large bushes. I was playing over there with one of her large cooking pots, off in my own little world. At one point while amusing and en...
Viscosity is the resistance of a fluid to flow. The molecules experience friction due to the molecular interaction among them. Different fluids with different viscosities flow at a different speed the more force the more viscous fluids of a fluid to flow is known to be the amount of thickness in any fluid for, example water would have low amount of viscosity and honey being thicker would have a high viscosity. Although viscosity can be known to be different depending on the density of the liquid. Force is required for any object to to travel the more viscosity that is in any liquid the more force is required
Many things change and alter how a hydrocolloid substance reacts. Factors added to hydrocolloid mixtures, such as water depending on the amount, can yield a gel or liquid substance. When heat is added or eliminated, the hydrocolloid mixture’s physical behavior changes. They may thicken at low doses to make a gel substance, some may be used as emulsifiers and others may also be used as whipping agents to create foams. When a hydrocolloid is dissolved in water, the water gathers around and is attracted to the sugar units, forming a layer of water with restricted movement. It is this ability to organize and control water that gives hydrocolloids their ability to thicken and gel. With the exception of gelatin, which is a protein, hydrocolloids are polysaccharides (fats) and or complex sugars (carbohydrates). Which is another interesting thing, Hydrocolloids come in all three forms of nutrients. The properties of any hydrocolloid are based on its physical structure (sugars made from) and its chemical properties: size, charge, and the
When the liquid level in both arms is the same, the pressure of the sample of gas inside the closed end must equal the pressure of the external atmosphere since the downward force on the two columns of liquid is then equal. When the liquid levels are unequal, the pressures must differ. The difference in pressure can be measured in units of length of the vertical column of liquid. The mm Hg, or its modern version the torr, originated in this use of the manometer. Mercury is particularly convenient for use in manometers (and barometers) because at room temperature it has low vapor pressure, does not wet glass, and has a high density. Other liquids such as linseed oil or water have also been used in manometers.
The foundations of fluid mechanics really crystallized in the 18th century. One of the more famous scientists, Daniel Bernoulli (1700–1782, Dutch-Swiss), point...
First, I went to pick up my stepson from the day care. To make sure he stayed warm I decided to let the car run while I ran inside to get him. Being just a quick run inside, I decided to leave the car unlocked. After returning to the vehicle, I strapped him to his car seat and then we proceeded to the grocery store. I kept running through my mind all the things that I needed to buy. Being a little preoccupied with all the traffic and not paying attention, I passed the grocery store and had to turn around and go back.
