The main purposes of an airspeed indicator in an aircraft?
The primary purpose of an airspeed indicator in an aircraft is to give the pilot some sense of how fast the aircraft is moving. A pitot tube, which is a forward pointing hollow tube that is mounted on the plane, is pressurized by the force of the air the plane encounters as it flies. This air pressure is compared to a static reference, and the difference is proportional to the airspeed. The faster the plane moves, the higher the pressure in the pitot tube, and the greater the difference between that and the reference. All that will result in higher indicated air speed. There are some issues associated with the accuracy of the system (like when the plane is flying into a headwind), and information on that and more detail in general can be found by using the link to Wikipedia. The pictures are informative, and a reader can pick up a handful of specialized terms relating to the device and the principles upon which it operates.
Answer
The airspeed indicator provides the pilot with an indication of relative airspeed -- or how fast the aircraft is moving relative to the air in which it is flying. This is important to a pilot because it is relative airspeed that affects the performance of the airplane. If airspeed gets too low, the plane will stall; if airspeed gets too high, the plane will suffer structural damage/failure. By monitoring airspeed, and making necessary control adjustments, a pilot ensures that the airplane performs as designed. Fortunately, aircraft are designed -- and pilots are trained -- such that these extreme cases are routinely avoidable.
What recording techniques used by the beatles are still used today?
Multi-track analog tape recording is still used today (although not commonly).
A Morrison table (also known as a Morrison shelter) was a bomb shelter used in WWII that could also be used as a table in a house.

Reason for yellow color in silver nanoparticles?
Basically without math, certain metals have elecrons that are "free" silver is one of these metals. These free electrons are necessary for a condition called a surface plasmon to exist. Now silver particles in an aqueous solution will have two parts to its refractive index, that of the water and that of the silver nanoparticles. Next is the interaction of light. Photons can be thought as particles or waves, in this case we will think of them as waves. When an electromagnetic wave interacts with the surface plasmon mode it causes the free electrons that are part of the surface plasmon to oscillate, usually in anti phase to the electromagnetic wave. This essentially causes certain wavelengths of light to be blocked from propagating, causing them to be reflected and giving the colour that you see.
Im actuallydoing some research on silver nanoparticles at the moment, and we can change this colour from yellow to almost anything that we want. For a yellow colour we see a plasmon resonance peak ca. 420nm but based on the size and shape of the silver nanoparticles we can tune the plasmon resonance peak.
Mie theory can be used to calcuate the extinction co-efficents. The reason why this is also called the surface plasmon is that the light waves will not penetrate more than 50nm so the interactions at the surface are the most important.
What is meant by mass curve in hydro power plant?
Mass curve is a plot of the cumulative inflows and outflows versus time used for calculating the storage capacity of a hydro unit.
How do you convert angstroms to meters?
multiply the # of angstroms times 10e-10 :) hope this helps you. :D
What problems could result from incorrectly converting measurements from one system to another?
blunders in technology
How do you escape a stall in flight on engineering com?
you can escape a stall in flight by rapidly pressing space but you cant escape a stall unless you get the emergency booster upgrade
What is the importance of engine watchkeeping?
Engine watch keeping duties include monitoring the ship's dials and gauges that can indicate malfunction needing immediate correction. Once any abnormalities are detected it the watcher must notify proper personnel.

A man-made levee is made by making the slope with soil we buy. A natural levee is formed when a river floods over its banks, the water spreads out, slows down, and deposits its load of sediment. Over time, the river's banks are built up above the level of the rest of the floodplain. he resulting ridges are called natural levees.
What effect did the artillery in ww1 on men?
Well, the constant bombardment of shells could cause the mental illness of shell shock. the symptoms being headaches, giddiness, lack of concentration and so on.... If men had shell shock they could not cope with the overwhelming pressure and so used to attempt to escape but were usually caught and were shot at dawn or tied to a post within the range of the enemy fire so they would be killed.
Not nice.
So men were lucky to survive the artillery fire - they could be killed by a direct hit or the effects of the explosion.
On a pedestal drill the workpiece is static and the drill is in a vertical position and rotates. On a lathe the workpiece rotates but not the drill, and the drill is in a horizontal position.

What is the function of solar cooker?
The solar cooker has three major functions. The first function is concentrating the light from the sun into one small area. Reflective materials are used to do this, and the result is that the heat is more concentrated in the solar cooker. The second function is turning the sunlight into heat. This is accomplished by using a substance that can absorb the heat from the sun and store it for cooking purposes. The third function is trapping the heat created by the sunlight. Trapping the heat helps to cook food more evenly and means that the solar cooker can be used on both hot and cold days.
