If you have any questions, please feel free to contact us. Sie erwerben hier das das wohl älteste, einfachste und bekannteste Barometer zur Luftdruckmessung unserer Zeit, im Volksmund auch Goethe Barometer gennant.Das Prinzip eines Flüssigkeitsbarometers wird bei diesem Barometer genutzt, welches man auch als Goethe-Glas, Goethe-Wetterglas, Donnerglas oder Wetterglas bezeichnet. Hierbei handelt es sich um ein, bis max. zur Hälfte mit eingefärbten destilierten Wasser gefülltes Barometer, welches an der Unterseite einen nach oben gestülpten und zur Atmosphäre hin offenen Schnabelhals besitzt, während das Hauptgefäß selbst gegenüber dem Luftdruck abgeschlossen ist. Bei niedrigem Luftdruck (schlechtes Wetter) steigt daher der Flüssigkeitspegel im Schnabelhals und sinkt dementsprechend bei hohem Luftdruck (schönes Wetter) . Zwar hatte Goethe ein solches Barometer in seinem Besitz, jedoch war er nicht der Erfinder dieses Barometertyps, wird aber seither nach Ihm bennant. Details: Höhe: 23 cm Breite: ca. 9 cm Gewicht: ca. 100g Material: 100% Glas Jedes einzelne Barometer ist Mundgeblasene Handarbeit , geringe Abweichungen in Form und Größe vorbehalten! � Einzelheiten zum Versand/ Bezahlung: Versandkosten inkl.

That case, the horsepower will not change from the humidity percentile change, although it will change from the temperature difference. Tuning for humidity can be complex.Many tuners use water grains as a measure of how much moisture is in the air. Water grains in the air are less affected by the temperature. Tuning with water grains is often based on the tuner’s database generated through trial-and-error.BarometerDuring a racing event, barometer values can change by a half inch on the mercury scale. That amount of change, by itself, can affect horsepower by almost 2% in some racing engines. Barometer indicates the weight of the air. Lower elevations indicate higher barometer values where air is more dense. Higher elevations indicate lower barometer values where air is less dense. Changing barometer values at a specific location can also indicate an incoming storm system where rain and wind are possible, indicating a temperature change or a humidity change.ElevationNot only does higher elevation indicate thinner air, it also affects the barometer values as mentioned above. Barometer taken from a local weather report is adjusted to sea level to provide a standard measurement, referred to as a corrected barometer. Higher elevations will have a much lower unadjusted barometer value. For example, a corrected barometer at Denver can be typically 29.9 inches of mercury. A typical uncorrected barometer in Denver, Colorado would be 24.5 inches of mercury. It is this unadjusted value that is most useful in engine tuning since this represents the actual localized air pressure data. Note that there is approximately one inch of barometer reduction on the uncorrected scale for every 1000 foot elevation increase.WindWind does not necessarily affect the air density measured at a location, but it can have a huge effect on the aerodynamics of the racing vehicle performance. Racing into a head wind puts more air drag from wind resistance on the racing vehicle body. However, it makes more power with racers with forward facing air scoops. The increased speed of air going into the engine increases the volume and oxygen from the air. Racing into a tail wind can reduce drag on the car body but also provide less power for engines with forward facing air scoops.Effects of weather on a racing vehicleAltitude of a racing facility has a dramatic effect on the barometric pressure in the air. Higher pressure from lower altitude makes more power with the proper tune-up. Measurement of the weather values become vital, especially for racing teams that travel to different locations. Changing weather and wind affect the aerodynamic drag on a racing vehicle body. Racing vehicles with ram air induction are affected by the alignment between the wind heading and the racing vehicle heading.On the

A glass barometer, sometimes called a water barometer, is a simple tool for measuring air pressure. It was invented in the 16th century and fascinated the German writer and philosopher Johan Wolfgang von Goethe, who used one extensively to measure local weather conditions. It consists of a teapot-shaped glass vessel that is completely closed except for the spout. Air pressure causes the water in the spout to rise and fall, and if the pressure is extremely low, such as just before a tornado or hurricane, water can actually come gushing out of the spout. A glass barometer is also known as a storm glass. How Does a Glass Barometer Work? How Does a Glass Barometer Work?The water level inside of a water barometer completely covers the outlet where the spout meets the body of the barometer. A small volume of air sits inside the vessel, creating a small reservoir of water inside the spout. Because the spout is open to the atmosphere, the surrounding air applies pressure to the water in the spout, which causes the water levels in the vessel and spout to rise and fall by a small amount. Because the air in the vessel is enclosed, the air compresses and decompresses with the rise and fall of the water level, creating, in effect, a standard by which to compare the surrounding air pressure.If the outside air pressure is higher than the air pressure inside the vessel, the water level in the spout will go down because the increased air pressure pushes down against the water in the spout. At the highest barometric pressure, the water that was in the spout may disappear into the vessel. Conversely, the spout level will rise when the surrounding air pressure is low, because the higher pressure of the air inside the vessel pushes against the water in the vessel, which in turn pushes up the water in the spout; the water in the spout faces less resistance and pressure from the outside air. If the outside air pressure is extremely low, water can actually spill from the spout. How to Fill a Water Barometer How to Fill a Water BarometerWhen you fill the vessel with water, it's important to maintain the air inside at the current atmospheric pressure to provide a standard against which to measure future fluctuations. To do this, you need to introduce water without letting air escape. There
