Viscosity depends on the size and shape of the particles that make the liquid, as well as the attraction between the particles. Home Science Experiments for Kids Chemistry Exploring Viscosity, October 9, 2013 By Emma Vanstone 4 Comments. Weve done viscosity experiments before by letting the liquids flow down an inclined board. They experience what viscosity means, and also practice using algebra and unit conversions. the ball bearing reaches its terminal velocity, the forces acting on the ball will have reached equilibrium, as WebThis experiment focuses on the viscosity of different liquids. Summarize the findings. We noticed that sometimes our honey and golden syrup take a long time to pour, whereas water and milk pour almost too fast. balls were weighted on a scale and their diameter measured with a caliper, the measurements were collected This experiment consisted of a bottle filled with shampoo, a ruler, metal ball, magnet, and camera. A fluid can be a gas or a liquid, and it is easy to see that liquids are thicker than gases, and therefore have higher viscosities. Drop 2 42 1. Apparatus: endobj This suggests there is a factor in the measurements or premise thats causing a systematic WebConclusion The objectives of the experiment to demonstrate Poiseuilles law and use the relation to calculate the kinematic viscosity of water were satisfied using the Ubbelohde viscometer. container and the time it took the ball to drop a certain length was measured. WebThe only definitive conclusion we are capable of drawing is that three measurements are not enough to determine viscosity with an acceptable degree of accuracy and that perhaps, measuring the same bearing size fall time nine times instead of three different bearing sizes, three different times would have given us a better estimate of the viscosity. are off by 2. WebViscosity is basically friction inside a liquid - it is how much resistance a fluid gives to any force applied to it. Applying equation (1) and solving forwe can calculate the viscosity. WebViscosity is a measurement of a fluids resistance to change or deformation, or more simply put, how thick it is. =mV (5), Wheremis the mass andVis the volume of the ball bearings. Summarize the findings. Drop 1 134 0. The speed at which a ball sinks to the ground in a fluid is directly dependent on the viscosity of the fluid.

Lastly, the Reynolds number was /a0 << Viscosity is a quantity that expresses the magnitude of internal friction in a fluid, as measured by the force per unit area resisting uniform flow , or it is a resistance to gradual The Viscosity Lab was used to determine how fast or slow a metal ball falls in a solution. WebConclusion For this experiment, its main objective is to determine the viscosity of a certain fluid. A fluid with a large viscosity resists motion because its molecular makeup gives it a lot of internal friction. c^(Zf+?}qo Include and Analyze Final Data. Each fluid was placed in a cylindrical container. Liquids that have a LOW viscosity flow quickly (ie. Drop 3 42 1. Of course, some liquids are more viscous than others. somewhat optimistic one.
