Title: Viscosity of sweetened water

Hypothesis

The viscosity of water will increase when more sugar is added to the water.

Problem

How the viscosity of water affect the time of flow?Literature Review

• Viscosity
The resistance of a fluid to any deformations that is caused by shear stress and tensile stress is known as viscosity. It also refers to the thickness of a fluidsubstance. A fluid with a lower viscosity is referred to as thin fluid and a fluid with a high viscosity is called a thick fluid. Viscosity can also be considered as the internal resistance that a fluidmust overcome before it can flow. Fluidity is the lack of fluid resistance and the opposite of viscosity.
Viscosity in a fluid is caused by the friction between the molecules in the substance. Gassesand fluids consist of adjacent layers of molecules. When an external force or pressure acts upon the fluid, the friction between the adjacent layers of the substance will determine the deformationand flow response of the fluid.
A fluid’s viscosity is dependant on the temperature of the substance. Increasing the temperature will reduce the viscosity of the fluid and cause it to become thinner.Butter for example, is hard when kept in the refrigerator. It becomes soft at room temperature and melts to a watery consistency when heated. Cooking oil also thickens when it is kept in arefrigerator.
• Tensile stress
Tensile stress (or tension) is the stress state leading to expansion; that is, the length of a material tends to increase in the tensile direction. The volume of the materialstays constant.
Therefore in a uniaxial material the length increases in the tensile stress direction and the other two directions will decrease in size. In the uniaxial manner of tension, tensilestress is induced by pulling forces. Tensile stress is the opposite of compressive stress.

Structural members in direct tension are ropes, soil anchors and nails, bolts, etc. Beams subjected to...
