The inner cylinder is filled by 2.5 cm (0.98 in) of rain, with overflow flowing into the outer cylinder. Plastic gauges have markings on the inner cylinder down to 1 ⁄ 4 mm (0.0098 in) resolution, while metal gauges require use of a stick designed with the appropriate 1 ⁄ 4 mm (0.0098 in) markings. After the inner cylinder is filled, the ...
Should the tropical depression intensify further it is named and classified as a tropical storm, which has winds speeds between 34–47 kn (17–24 m/s; 39–54 mph; 63–87 km/h). [8] Should the system continue to intensify further then it will be classified as a severe tropical storm, which has winds speeds between 48–63 kn (25–32 m/s; 55 ...
The average relative humidity is 90% and the average temperature is 26.4 °C. [63] Quibdó, the capital of Chocó, receives the most rain in the world among cities with over 100,000 inhabitants: 9,000 millimetres (350 in) per year. [62] Storms in Chocó can drop 500 mm (19.7 in) of rainfall in a day.
The unit is named after Blaise Pascal, noted for his contributions to hydrodynamics and hydrostatics, and experiments with a barometer.The name pascal was adopted for the SI unit newton per square metre (N/m 2) by the 14th General Conference on Weights and Measures in 1971.
Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth.The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa), which is equivalent to 1,013.25 millibars, [1] 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.

The name SevenMeters derived from the realization that the water level will rise 7 meters if the global warming will melt all the ice in Greenland. In order to show what impact the possible climate change can have to the world, the SevenMeters group established 24 kilometers of red blinking LED-lights at 7 meters height during the UN's climate ...
Because they are used for domestic water measurement, piston meters, also known as rotary piston or semi-positive displacement meters, are the most common flow measurement devices in the UK and are used for almost all meter sizes up to and including 40 mm (1 + 1 ⁄ 2 in). The piston meter operates on the principle of a piston rotating within a ...
An industrial version of the fine-wire anemometer is the thermal flow meter, which follows the same concept, but uses two pins or strings to monitor the variation in temperature. The strings contain fine wires, but encasing the wires makes them much more durable and capable of accurately measuring air, gas, and emissions flow in pipes, ducts ...
