Uncertainty Principle. is born: one cannot, with absolute certainty, know both the velocity and position of a moving body.. NON NEWTONIAN FLUIDS du Scene 1. Without looking at your texts:. In which year is scene 1 set?. How many of the characters from scene 1 can you remember?. Make a character tree/list for scene 1. What happens in scene 1? Write a brief summary.. Fluids. A fluid is anything that flows: liquids and gases. One . common characteristic is that fluids have no fixed shape and are easily . deformed: . t. ake the shape of their containers.. Density. The density of a substance is the quantity of matter contained in a unit volume of the substance. . Viscous Fluids. Viscosity is how engineers measure the resistance of fluids when being . deformed:. τ. = . μ. (du/dy. ). The less viscous the fluid, the greater its ease of . movement.. Viscosity is useful for calculating the force needed to move a fluid. For example, in these industries: . Quiz 7 – 2014.01.10 . Question (15 . mins. ). A small capillary with an inside diameter of 2.22 .  10. -3. m and a length 0.317 m is being used to continuously measure the flow rate of a liquid having a density of 875 kg/m. e. r . N. o. n. -.
