What is natural laminar flow?
[¦nach·rəl ′lam·ə·nər ′flō] (aerospace engineering) Airflow over a portion of the wing such that local pressure decreases in the direction of flow and flow in the boundary layer is laminar rather than turbulent; frictional drag on the aircraft is greatly reduced.
What are 2 characteristics of all fluids?
Lesson Summary While each phase has unique properties, they also share some properties. This is how we can categorize both liquids and gases as fluids because they are both materials that flow. Fluids have common properties that they share, such as compressibility, density, pressure, buoyancy and viscosity.
What property of water is most important for living organisms?
Water has the unique ability to dissolve many polar and ionic substances. This is important to all living things because, as water travels through the water cycle, it takes many valuable nutrients along with it! Water has high heat capacity.
What are the 8 properties of water?
Terms in this set (8)
- Surface Tension. Cohesion allows water to pull together & forn droplets; or form an interface between it & other surfaces.
- Adhesion. Sticking of one stubstance to another.
- Imbibition.
- High Specific Heat.
- Cohesion.
- High Heat of Vaporization.
- Frezzing & Expansion Of Water.
- Versatile Solvent.

Why is liquid water important for life?
Even organisms that live in very dry places need water to live. One reason that water is so important is because it’s a liquid. This means that it can move around the materials that are needed for chemical reactions. These reactions include the ability for cells to get energy in and to move waste out.
Why is water called a universal solvent?
And, water is called the “universal solvent” because it dissolves more substances than any other liquid. This allows the water molecule to become attracted to many other different types of molecules.
Why is water so special?
The heat capacity of water is more than twice the heat capacity of natural mineral and rock material. This tends to even out temperature differences on Earth, from day to night and from summer to winter. Water is also the best all-around solvent. More solid substances dissolve in water than in any other liquid.
What liquids dont contain water?
Bromine and mercury are liquids are room temperature and, when pure, have no water in them. Pure solvents and compounds (other than water) have no water. Gasoline does not (or should not) have water in it, however, ethanol, which can be in gas, absorbs and holds water.
Do you need water for life?
To stay alive, the organism takes in important materials for making energy, while shuttling out toxic substances such as waste products. In this regard, water is essential simply because it’s a liquid at Earth-like temperatures.
Why is water so rare in the universe?
But water isn’t that rare in the cosmos. Water is made of hydrogen and oxygen. Hydrogen is by far the most abundant element, and Oxygen is the third most abundant. Number two is helium, which doesn’t react chemically, so water is really common.
