1) Define Viscosity. It is a measure of fluidity of the system. Many fluids undergo continuous deformation with the application of shearing stress. 2) Define Newtonian fluids If the force flow relation is linear then the fluid is Newtonian . 3) Define Non Newtonian fluids If the force flow relation is non linear then the fluid is Newtonian . 4) Define Kinematic Viscosity. Ratio of absolute viscosity to the density of the fluid. V= µ cm2 /ς sec 5) Define Specific Viscosity. Ratio of absolute

questions refer to Activity 2: Studying the Effect of Viscosity on Fluid Flow. 5. At what viscosity level was the fluid flow rate the highest? 1.0 6. Describe the relationship between flow rate and viscosity. The relationship is inversed; meaning a fluid that has a high viscosity has a slow flow because it resists the flow. Fluid that has a low viscosity will flow faster because it is less resistance to the flow. 7. Was the effect of viscosity greater or less than the effect of radius on fluid

FUEL OIL BURNERS By Mark Butterfield March 09 INTRODUCTION The history of burners dates back to the early shipping days‚ when fuel oil first started replacing coal as the ships’ primary fuel source. Since then‚ burner designs and construction have come a long way‚ but the principles behind their operation has remained the same. All makes and types of burners have two things in common They need to atomise the fuel They need to mix the fuel with the air needed for combustion

conductivity and thermal diffusivity. When considering the heating or cooling of foods‚ some other physical properties must be considered because of their intrinsic relationship with the ‘‘pure’’ thermal properties mentioned‚ such as density and viscosity. Therefore‚ a group of thermal and related properties‚ known as thermophysical properties‚ provide a powerful tool for design and prediction of heat transfer operation during handling‚ processing‚ canning‚ and distribution of foods (Fig. 4.1).

factor affecting the viscosity of a mixture of liquid Research Question The effect of hydrogen bonding on resisting flow of five different liquids Background Theory Viscosity is the resistance of a fluid to flow‚ either within itself‚ or to moving past an objects moving through it. A liquid with high viscosity is thick and flows slowly. A liquid with a low viscosity is thin and flows quickly. Different liquids have different viscosities. Factors‚ which affect viscosity of a liquid‚ are:

(10 pts) In a falling ball viscometer‚ a steel ball with a diameter of 0.25 inches is allowed to fall freely in a heavy fuel oil having a specific gravity of 0.86. Steel weighs 0.283 lb/in3. If the ball is observed to fall 12.00 inches in 10.4 seconds‚ calculate the dynamic viscosity of the oil in lb-s2/ft. ENT 310 Fluid Mechanics Midterm #1 Page 2
