How is viscosity used in everyday life?

Water has a low or “thin” viscosity, for example, while honey has a “thick” or high viscosity. The law of viscosity has important uses in such areas as inkjet printing, protein formulations and injections, and even food and beverage manufacturing.

What are the uses of viscosity?

Viscosity measurements are used in the food industry to maximize production efficiency and cost effectiveness. It affects the rate at which a product travels through a pipe, how long it takes to set or dry, and the time it takes to dispense the fluid into packaging.

Why is viscosity important in engineering?

Knowing the viscosity helps engineers know how a fluid will behave under different circumstances. Engineers also use this equation when designing devices. By using a fluid with a known viscosity and applying a force to it, engineers can calculate how fast the fluid will move.

What is the effect of temperature and pressure on viscosity?

The shear viscosity of the liquids that are used as lubricants increases with increasing pressure and decreases with increasing temperature and, at sufficiently large stress (rate), decreases with increasing shear stress (shear rate).

What is effect of pressure on viscosity?

It has been observed that above about 33° C the viscosity of water increases with pressure, and that below this temperature, initially the pressure effect is negative but at about 1,000 kg/cm2 the viscosity relative to 1 atm.

How does surface tension work?

Surface tension in water owes to the fact that water molecules attract one another, as each molecule forms a bond with the ones in its vicinity. Due to the surface tension, small objects will “float” on the surface of a fluid, as long as the object cannot break through and separate the top layer of water molecules.

What is surface tension and what causes it?

The surface tension arises due to cohesive interactions between the molecules in the liquid. At the bulk of the liquid, the molecules have neighboring molecules on each side. Molecules are pulling each other equally at all directions causing a net force of zero.
