Absolute Error 2. A fluid with large viscosity resists motion because its molecular makeup gives it a lot of internal friction. The sample viscosity correlates with the time required by the ball to drop a specific distance, and the test results are given as dynamic viscosity. (3) Viscosity is an intrinsic property of the fluid, although it can depend on temperature (in some cases, quite strongly). error is below 0.1 percent. Do you think the liquid will impact what happens when a marble is placed into each jar? Fluids for which the shearing, stress is directly related to rate of shearing strain are, which shearing stress is not directly related with, hence the term apparent viscosity is used for these. VISCOSITY VISCOSITY OF WATER BY CAPILLARY FLOW REFERENCES D.M. Objective Analysis for diesel engines in cogeneration plant. What I want to know is the problems that can occur during a standard classroom experiment that could effect the … Uncertainty is always a component of chemistry. substance melts (change in state from Solid to Liquid). In laminar flows, fluid particles move in layers, sliding over each other, causing a small energy exchange to occur between layers. At times of high demand, the furnace supplies heat to the steam at a rate of at ℃ least 30MJ/s. Step 1 – Gather four clear glass jars and fill one with water, one with corn syrup, one with cooking oil (we used vegetable oil, but any cooking oil will work) and one with honey. You will do formal lab reports for two of the first four experiments (viscosity of polyvinyl alcohol solutions, mutarotation of glucose) and informal lab reports for the other two experiments (dipole moment of polar molecules in solution, lattice energy of argon).

How Does the Consistency of a Liquid Impact Magnetic Attraction, 4 clear glass jars of the same size (we used pint-sized mason jars). Viscosity is a measure of a fluid’s resistance to flow. By definition, experimentation is a procedure for testing (and determination) of You’ll notice right away that the marble behaves differently in each jar. Wolfram Language Revolutionary knowledge-based programming language. The question answered in this experiment is: how does the consistency of a liquid impact how long it will take for a marble to sink in a jar of that liquid? It also contains ideas on how you can expand on the experiment. Your job is to come up with some designs. Kinematic viscosity has a strong dependence on temperature. Viscosity of liquids is often very temperature sensitive, with most liquids and gases becoming less viscous (thinner) as they heat up. It is the ratio of density of a fluid to the density of, It is basically the resistance to flow for a fluid. I'm doing an experiment write up for the young modulus. JUMP TO SECTION: Instructions | Video Tutorial | How it Works. 2015/2016. dispersion, forest fires, volcano behavior, oceanography etc. Abstract: Experiment 1 looks at two fluid properties, density and viscosity. Article is related to corporate social responsibility (CSR) in Pakistan. For the liquids it increases, with the increase in temperature whereas it decreases, for the case of gases. Four marble balls were chosen and their diameters, converting the existing process plant into a cogeneration plant to meet both their process-heat and power requirements. Lab 1 - Viscosity Lab Report. Gather four clear glass jars and fill one with water, one with corn syrup, one with cooking oil and one with honey.Carefully drop one marble into each jar. hence an increase in viscosity. also have caused inconsistency in values. You are required to use a modern engineering tool to solve the problem. Drop one marble at a time and observe what happens to the marble when it enters the liquid. In nature and in laboratory experiments, flow may occur under two very different regimes: laminar and turbulent. 3: Temperature dependence of the viscosity of the Cooking Oil (enough to fill one jar) ","position":2,"name":"Carefully drop one marble into each jar. Errors can arise from many sources. Then propose your design for the cogeneration plant complete with pressures and temperatures and the mass flow rates.
