Retrieved from https://paperap.com/paper-on-viscosity-lab-report/. Whereris the radius of ball bearings. From the pressure diagrams, it was concluded that there was a high-pressure gradient at the leading edge and decreased through the aerofoil. that the premise and assumption of laminar flow was a somewhat optimistic one, especially so in the case of water, rubbing alcohol, and vegetable oil). Sorry, preview is currently unavailable. Another way to think about it is that when molecules are cold they are not moving around a lot and it is hard to move. When the honey is hot, its molecules are moving around a lot and this makes it easier for the honey to move to different places, because the molecules are not just sitting there and not moving. Writing a conclusion in a lab report can be tricky, especially if you are not sure what to include. Higher the viscosity of liquid bitumen, the more nearly it approaches a semi-solid state in consistency. We will include tips on formatting and structure, as well as how to effectively communicate your findings. Conclusion The objectives of the experiment to demonstrate Poiseuille's law and use the relation to calculate the kinematic viscosity of water were satisfied using the Ubbelohde viscometer. Drop Frames 240 /s Velocity[m/s] The results can be seen in table 8, uncertainty is The temperature of the fluids was measured with a thermometer, see table 2. You can also try other liquids. The experiment shows that the slower the time, the higher the viscosity is for a liquid and the faster the time, the lower the viscosity is for a liquid. The greater the. Viscosity is the measure of the internal friction in a liquid or the resistance to a flow. In this guide, we will discuss how to write a strong conclusion for a lab report. Stress is a measure of the average amount of force exerted per unit . Compare your results of the measurement of the viscosity with the accepted values. The first step is to restate the goals of the experiment. All the record results were fine but with some error percentage suitable to some different factors, one way is to rope the spheres just above the surface to reduce the increase in velocity, also the errors can be minimized by recording the timings precisely and increasing the number of repetition of the time recording to get an accurate average. It described the internal friction of a moving fluid. Experiment Biological Diversity [k6nqwo3ve1nw] 2022-10-13 . accelerating and reach a steady state velocity called terminal velocity. 4. you Similarly, if a fluid has less viscosity (thickness), an object can move faster through it. In everyday terms (and for fluids only), viscosity is "thickness". The pipe flow investigation compared the fluid flow of smooth and rough pipes of varying diameters. P1 - Practices digital signal processing are practices p1,p2,p3. calculated can be found in the tables bellow. I had to wait 37 minutes, 26.8s (2246.8s) for the metal piece to reach the bottom! EXPERIMENT TO DETERMINE THE VISCOSITY OF GLYCERINE. An adult had to help with the stove/ heating. Basically, they have an inverse relationship. Medium Re If the experiment did not meet its goals, be sure to explain why. Honey sure has high viscosity! Drop one marble at a time and observe what happens to the marble when it enters the liquid. Viscosity is a measure of the resistance of a fluid which is being deformed by ei- ther shear stress or tensile stress. Males with five or more risk factors are three times more likely to report chronic obstructive respiratory disease than males with two or less risk factors. Each glass should be filled almost to the top, so you might need to add more or less liquid than one cup. It is a measure of the resistance to flow. 0 NSA/AMA respectively. The time taken to travel between two marks on the beaker was recorded. A milkshake has a viscosity of $0.50 \mathrm{Pa} \cdot$ s. To drink this shake through a straw of diameter $0.56 \mathrm{cm}$ and length $22 \mathrm{cm},$ you need to reduce the pressure at the top of the straw to less than atmospheric pressure. Gas densities: mostly in the range of a few grams per liter. Motor Oil 22.
