How do you determine where the strongest winds are on a weather map?
The barbs are arrows pointing in the direction wind blows from. They have little points (barbs) off the side of them. A full barb represents 10 knots, a half barb represents 5 knots, and a flag represents 50 knots. You add the numbers represented by the number of full and half barbs. Thus 2 full barbs and 1 half barb represents a 25 knot wind. To convert knots to MPH multiply the knots by a factor of 1.15.
What is Bunsen burner and how it is used?
When the University of Heidelberg hired Robert Bunsen in 1852, the authorities promised to build him a new laboratory building. Heidelberg had just begun to install coal-gas street lighting, so the new laboratory building was also supplied with illuminating gas. Illumination was one thing; a source of heat for chemical operations something quite different. Previous laboratory lamps left much to be desired regarding economy and simplicity, as well as the quality of the flame; for a burner lamp, it was desirable to maximize the temperature and minimize the luminosity. While his building was still under construction late in 1854, Bunsen suggested certain design principles to the university's talented mechanic, Peter Desaga, and asked him to construct a prototype. The Bunsen/Desaga design succeeded in generating a hot, sootless, non-luminous flame by mixing the gas with air in a controlled fashion before combustion. Desaga created slits for air at the bottom of the cylindrical burner, the flame igniting at the top. By the time the building opened early in 1855, Desaga had made fifty of the burners for Bunsen's students. Bunsen published a description two years later, and many of his colleagues soon adopted the design. The device in use today safely burns a continuous stream of a flammable gas such as natural gas (which is principally methane) or a liquefied petroleum gas such as propane, butane, or a mixture of both. The burner has a weighted base with a connector for a gas line (hose barb) and a vertical tube (barrel) rising from it. The hose barb is connected to a gas nozzle on the lab bench with rubber tubing. Most lab benches are equipped with multiple gas nozzles connected to a central gas source, as well as vacuum, nitrogen, and steam nozzles. The gas then flows up through the base through a small hole at the bottom of the barrel and is directed upward. There are open slots in the side of the tube bottom to admit air into the stream via the Venturi effect, and the gas burns at the top of the tube once ignited by a flame or spark. The most common methods of lighting the burner are using a match or a spark lighter. The amount of air (or rather oxygen) mixed with the gas stream affects the completeness of the combustion reaction. Less air yields an incomplete and thus cooler reaction, while a gas stream well mixed with air provides oxygen in an equimolar amount and thus a complete and hotter reaction. The air flow can be controlled by opening or closing the slot openings at the base of the barrel, similar in function to a car's carburetor. If the collar at the bottom of the tube is adjusted so more air can mix with the gas before combustion, the flame will burn hotter, appearing blue as a result. If the holes are closed, the gas will only mix with ambient air at the point of combustion, that is, only after it has exited the tube at the top. This reduced mixing produces an incomplete reaction, producing a cooler but brighter yellow which is often called the "safety flame"or "luminous flame". The yellow flame is luminous due to small soot particles in the flame which are heated to incandescence. The yellow flame is considered "dirty" because it leaves a layer of carbon on whatever it is heating. When the burner is regulated to produce a hot, blue flame it can be nearly invisible against some backgrounds. Increasing the amount of fuel gas flow through the tube by opening the needle valve will of course increase the size of the flame. However, unless the airflow is adjusted as well, the flame temperature will decrease because an increased amount of gas is now mixed with the same amount of air, starving the flame of oxygen. The blue flame in a Bunsen burner is hotter than the red flame. Many lab accidents are related to burn injuries or exposed flames, and as a result new students are trained carefully in the use of a Bunsen burner. In general, the user should make sure that hair and clothing are secure, and unlikely to fall into the flame. In addition, flammable chemicals should be kept away from the Bunsen burner, and someone should remain by the burner at all times to supervise it. The flexible rubber hose connecting the Bunsen burner to the gas nozzle on the lab bench should also be secure, with no evidnce of leaking, and people should be cautious about touching things which have been exposed to the often considerable heat of a Bunsen burner, especially glass objects.
What are the two most commonly used flasks?
Laboratory Glassware: Types of Laboratory FlasksFlasks are useful tools for containing liquid and performing mixing, heating, cooling, precipitation, condensation and other processes. They come in a range of sizes, materials and uses. Commonly used laboratory flasks include:An Erlenmeyer flask, conical, or E-flask is one of the most commonly used flasks in scientific laboratories. The flask has a conical base that almost extends into a small, cylindrical neck. This shape allows the flask to be sealed with a bung for heating purposes, while also allowing a researcher the freedom to shake or stir the flask without spilling liquid. The Erlenmeyer flask has diverse uses such as holding and measuring chemical liquid samples, but can also be used to mix, heat and boil chemicals.A Büchner, or sidearm flask is essentially an Erlenmeyer flask (see above) with an additional small tube extending from the side of the neck. The bottom is conical in shape, with a short neck from which the small tube extrudes. The entire flask is made of thick glass. The small side-arm tube is composed of a hose barb, which is a serrated section that catches a thick-walled flexible hose. Because of this design, a Büchner flask is well-equipped for creating vacuums with the help of a Büchner funnel. With the funnel on top of the glass neck and a tube sucking the pressure out of the side, vacuums for sluicing liquids can be created very easily within the flask.A fleaker is a portmanteau of the words flask and beaker, and physically resembles a combination of an Erlenmeyer flask and a beaker. The cylindrical body culminates in a neck that curves inward before flaring out in a rounded opening. Fleakers are generally used for similar applications as Erlenmeyer flasks, but most often only for liquids.A Florence, or boiling flask is a large, round sphere with a long, thin neck and a slightly flared rim opening. The rounded design of the bottom is such that a Bunsen burner can easily heat the solution within. Some Florence flasks are produced with rounded bottoms, and thus need support in order to stand upright; others have flat bottoms and can stand alone. Because they are so often used for boiling, Florence flasks are produced with borosilicate glass to prevent cracking.A retort is a type of flask used primarily for distillation and its design is exclusive to this purpose. The retort resembles an exaggerated teardrop with the middle bent at almost a 90 degree angle. The bulb portion contains a liquid or chemical solution, which is heated to the point of condensation. The condensation then attaches to the roof of the retort, and as it begins precipitating, it runs down the angle of the long, thin point of the tear where there is another opening. The liquid collects in a separate container.A Schlenk flask can be a round, pear-shaped or tubular bulb that stretches vertically into a long, thin neck with a side-arm. The side arm features a valve so that pressure or gas can be released from the flask.Volumetric flasks are flasks used to measure specific volumes of material. They are generally gradated with metric markings to measure the volume of material in the container. They are typically composed of a round or pear-shaped bulb and a long thin neck topped by a stopper or rubber bung. Because they are generally used for measurement or reactions and not heating or boiling, they can be made of plastic or glass.-http://www.thomasnet.com/articles/instruments-controls/types-of-lab-flasks
