What is the kinematic viscosity of sea water?

What is the kinematic viscosity of sea water?

The dynamic viscosity of water is 8.90 × 10−4 Pa·s or 8.90 × 10−3 dyn·s/cm2 or 0.890 cP at about 25 °C. Water has a viscosity of 0.0091 poise at 25 °C, or 1 centipoise at 20 °C….Water – Density Viscosity Specific Weight.

Is seawater more viscous than freshwater?

The viscosity (i.e., internal resistance to flow) of seawater, for example, is higher than that of fresh water because of its higher salinity. The density of seawater also is higher.

Which is denser seawater or freshwater?

Saltwater is more dense than freshwater. For example, the density of freshwater in the Mississippi River in southern Louisiana is 0.999. The density of saltwater at Japanese ports is 1.025.

How does saltwater compare to freshwater density?

Salt water is more dense than fresh water Density = mass/volume. Increasing the mass by adding salt increases the density. Seawater is a little bit more dense than fresh water so it sinks beneath freshwater. This means that when rivers flow out into the sea the river freshwater floats on top of the sea water.

What is kinematic viscosity and its units of measurement?

The kinematic viscosity is defined as the ratio of the dynamic viscosity to the density of the fluid. The kinematic viscosity is referred by the term ν (Greek letter nu). Kinematic viscosity has units of meters squared divided by seconds. The unit ‘stoke’ is also used to measure the kinematic viscosity.

What is the significance of kinematic viscosity?

Kinematic viscosity is a temperature dependent property . In industrial applications, kinematic viscosity becomes important in fluid transport and lubrication. The latter relationship relates to corrosion protection when choosing a lubricant for its protective qualities. Viscosity results from the intermolecular forces between molecules in a liquid.

What is the SI unit of kinematic viscosity?

The SI unit for kinematic viscosity is square meters per second (m2/s). However, due to the viscosity values of most common fluids, square centimeters per second (cm2/s) is used more often. Note that 1 cm2/s is equivalent to 100 cSt.

What are 2 main factors determine the density of seawater?

The two main factors that affect density of ocean water are the temperature of the water and the salinity of the water. The density of ocean water continuously increases with decreasing temperature until the water freezes. Increasing salinity also increases the density of sea water. Temperature has a greater effect on the density of water than salinity does.
