Kindly tell me the physics behind pressure cooker, water flow from tank and aeroplanes

I would have to type you a book... lol. I actually just recently took an interest in physics. Started reading up on it. Here are a few books I've been looking through:

THE HYDROGEN BOND AND THE WATER MOLECULE THE PHYSICS AND CHEMISTRY OF WATER, AQUEOUS AND BIO-MEDIA ~ Marechal, Yves

High-Voltage Electrical Breakdown of Water ~ Kristiansen, M.

Water Flow In Soils ~ Miyazaki Tsuyoshi

Applied Fluid Mechanics ~ Robert L. Mott

Aqueous Systems at Elevated Temperatures and Pressures: Physical Chemistry in Water, Steam and Hydrothermal Solutions ~ Donald A. Plamer

Molecular And Particle Modelling Of Laminar And Turbulent Flow ~ Donald Greenspan

Enjoy! :)

Hope this helps.

physics behind pressure cooker,
water flow from tank
and aeroplanes


Pressure cooker:
Water boils at 100 C at sea level. When the pressure increases, the boiling point rises. On heating, when the vapor pressure of water equals the pressure of the outside atmosphere, the water boils.

Water is required in a pressure cooker. It heats up but can't boil because of the increasing pressure. Its vapor pressure (and temperature) continue to rise until the vapor pressure equals atmospheric pressure plus the pressure imposed by the "rocker". Eventually, it displaces the rocker. That is its maximum temperature.

Because its temperature is higher than boiling water, it cooks food faster.

Water flow from tank:
The pressure of the water depends on how high it is above the spigot where it's coming out. The potential energy is given by E = MGH where E is the potential energy, M is the mass of water, G is the acceleration due to gravity and H is the height.

The rate of flow of the water is given by Poisuelle's equation (Hagen-Poiseuille equation - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Hagen%E2%80%93Poiseuille_equation)) if flow is not too fast. Otherwise, you have turbulent flow.

Airoplanes:
"Lift" is what makes an airplane leave the ground and remain in the air. This is countered by "drag" which is frictional and gravitational in nature. "Lift" is dependent on the shape of the wing (Wing - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Wing)). Air moves over the top of the wing which is curved. Air also flows under the wing which is more straight. The air, therefore, moves faster over the top of the wing. This creates a low pressure on the top of the wing. This causes the "lift". Control surfaces (Aircraft flight control systems - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Control_surfaces)) are used to control the movement of the airplane.

Great way to put it Perito. Had to spread the rep... :(

Please can you explain me the unit motion and force.
