Student groups conduct a brief experiment in which they quantify the flow rate to understand how it relates to a fluid's viscosity and ultimately chemical composition they explore these properties in milk and cream, which are common fluids whose properties (and even taste) differ based on fat content. The rate at which different fluids flow can vary considerably so how about having races to test them what you will need: viscosity races is a great experiment investigating viscosity for ages 5 and up you’ll need a homemade ramp, an  reply viscosity races - making science fun for kids says. The rate of flow (this is what i will be measuring), in litres per second viscosity viscosity is the coefficient of proportionality between the frictional force and the product of surface area × velocity gradient (at the heart of a liquid. Observations/ results: during this experiment i observed that the oil that was at 6º was cloudy and thick it was very blurry and cloudy when you looked through it it had a very high viscosity and a low flow rate. The value for the viscosity of water now generally accepted, 1002 cp at 20°c and 1 atm, was reported by swindells, coe, and godfrey (scg)  in 1952 based on work which extended over a period of some twenty years these pairs t he rates of flow reported covered a range.
Experiment 1: viscosity of liquids victoria kulczak lab partners: laina maines & heidi osterman date of lab: 2/21/11 poiseuille’s law is given in equation 1, in which dv/dt is the volume flow rate, r is the radius, l is length of the tube, δp is the pressure difference across the ends of the tube and η is the viscosity. Flow rate/viscosity experiment question: which of the following substances, shampoo, salad dressing, ketchup, chocolate syrup, dish soap and corn syrup is the most viscous and has the slowest flow rate. All of the instructions are found on the back of your flow rate experiment sheet viscosity questions assigned: jan 8th due: with binder: for this task you were given a period to work on a series of review questions having to do with viscosity any questions not done were to be completed as homework. Viscosity is a property of a liquid and is defined as the resistance of a liquid to flow the purpose of this experiment was to determine if the temperature of a liquid affects the viscosity of the liquid.
A few reference labs in the us do test the viscosity of whole blood but are only able to measure high shear viscosity (at a shear rate of 90 s-1) this is like testing blood pressure with a cuff and only being able to measure a single value for systolic blood pressure, instead of both systolic and diastolic. 4 discuss the effect that polycythemia would have on viscosity and on blood flowyour answer:polycythemia is an exponential increase in the red blood cells this would result in an increase in viscosity and a corresponding decrease in blood flow exercise 5: cardiovascular dynamics: activity 3: studying the effect of blood vessel length on blood flow rate lab report pre-lab quiz resultsyou. Full answer viscosity is affected by temperature, and fluids at higher temperatures tend to flow more easily predictions of flow rate are possible when the viscosity and forces known are involved, as long as the fluid is not compressible and the flow is laminar. Sometimes viscosity values are shown in terms of the equivalent units of n m -2 s or pa s, where the pascal (pa) is the si unit of pressure and is equal to 1 newton per square meter (table a-1. You determine viscosity by measuring the flow rate of the fluid flowing through the capillary tube and the pressure differential between both ends of the capillary tube this measurement method is based on the laws of physics therefore, this is called the absolute measurement of viscosity.
Lesson fluid flow grade: 8 strand: fluids critical learning: big ideas how does the flow of fluids affect our lives focus questions what factors affect the flow rate of a fluid how are viscosity and flow rate connected curriculum expectations devise an experiment to find out how the flow rate of a fluid is affected by changing its. Polymer testing and analysis iso 17025 accredited lab polymer analysis employs both physical and analytical methods to verify the chemical, mechanical, and thermal properties of a polymeric material. Fluid flow viscosity poiseuille's law flow rate corn flour and water mixture is another non-newtonian fluid viscosity in an experiment water rose by capillary attraction through two columns of soils, one with coarse grains and the other with fine gains.
The final experiment had possible errors due to the experimental flow (white, 2003) more specifically, it determines the fluid strain rate that is generated by a given applied shear stress plane couette flow is a simple fluid flow example that flow the viscosity can be determined from the velocity of the rotating cylinder. Pump selection for laboratory scale fluid handling useful for tiny flow rates, generally used for microfluidics ideal for pumping high-viscosity fluids that will not flow well through a standard impeller type pump the oil pump in most automobile engines is a gear pump. A laboratory experiment on inferring tube, respectively, η is the viscosity of the ﬂuid and p is the pressure difference between the ends of the tube flow rate q as a function of the difference of pressure p for tubes of r = 088 mm and different lengths, l table 1. Problem statement: we are measuring the flow rates of liquids of different viscosities through holes of varying sizes we ultimately want to observe the relationship between the viscosity and the flow rate, and also between the diameter and the flow rate. Question: joel white of weyerhaeuser was curious about the effect of flow rate, contaminant level, and viscosity on the performance of a filter, comparing the multi-pass beta test (iso 4572) performance to the real world.
Ech 4224l unit operations lab i fluid flow 1-5 let us discuss how one can determine flow rates q 1 and q 2 through the pipes 1 and 2 if the total flow rate q is known the mass balance for this system can be written as. Here is a video on an experiment conducted to see how temperature effects viscosity and flow rate, and also both topics in general. • identify factors that affect the flow rate of fluids • design an experiment to measure the flow rate of fluids viscosity and flow rate viscosity, density, and compressibility are all properties of fluids 213 figure 86 the particles in a solid (a) and a liquid (b) are packed closer together than the. Viscosity lab procedure: teacher manual goals: understand what viscosity is designed to distribute a certain amount of fuel at a certain rate, which is affected by fuel viscosity the honey has a much higher viscosity, or resistance to flow, in comparison to the water.
