The viscosity of the blood not only influences the estimation of those parameters but is often a parameter that is of great interest to both doctors and engineers. CHECK THAT YOU ARE CALCULATING FOR THE CORRECT UNITS! Viscosity quantifies a material’s resistance to flow. A common question often asked by our customers is the reason why flow rate is reported on datasheets of liquid-dispensed thermal interface materials instead of viscosity. What is the flow rate when the pump operates at 80% speed? Quiz. Viscosity is a crucial parameter for measuring the flow of fluids, such as liquids, semi-solids, gases and even solids. Good luck! Viscosity Viscosity is a liquid’s internal resistance or friction that keeps it from fl owing. It should take about 30 minutes to complete. In other words, it is the “thickness” or “thinness” of a fluid. Flow Rate and Viscosity. It should take about 30 minutes to complete. You will also use the particle theory to explain some behaviours and properties of fluids—liquids and gases. 030226 Quiz 4 Polymer Processing 1) ... indication of the dependence of viscosity on rate of strain. Equations Page (found here). For a flow meter, what is application maximum and what is meter maximum? They are inversely proportional to each other. Viscosity depends on the size and shape of the particles that make the liquid, as well as the attraction between the particles. Experiment: HONEY Vs.
