column of mercury

He found himself staring at the column of mercury in the weather glass.

A special unit that measures pressure shows how high a column of mercury rises.

Blood pressure is measured in a column of mercury.

Or on a slender column of mercury, that unstable element.

The next day, March 27th, the column of mercury rose in the barometrical tube.

The column of mercury fell to about 76 cm, leaving a Torricellian vacuum above.

Such barometers are an enclosed column of mercury, designed to be open to the atmosphere to measure atmospheric pressure.

Green encased his instrument in a simple metal tube, which admitted of the column of mercury being easily read.

Keep squeezing until the dial or column of mercury reads about 30 mm Hg higher than your usual systolic pressure.

When the temperature falls, the column of mercury breaks at the constriction and cannot return to the bulb, thus remaining stationary in the tube.

Barometric pressure is measured as the height in inches to which the atmosphere will force a column of mercury in an evacuated tube.

A cylindrical column of mercury 10mm diameter carries a current of 100 A uniformly distributed over the cross-section.

The classic measurement device is a mercury sphygmomanometer, using a column of mercury measured off in millimeters.

A channel in a column of mercury, with receiving and transmitting quartz piezo-electric crystals mounted at opposite ends.

They measure blood pressure by observing the height of a column of mercury; once made, errors of calibration cannot occur.

His solution used a column of mercury with piezo crystal transducers (a combination of speaker and microphone) at either end.

For another hour I saw that pitiless column of mercury rise and rise until at four hundred and ten miles it stood at 153 degrees.

The mighty debts of each great European Power stand like so many columns of mercury, for ever rising and falling to indicate the pressure upon each.

Thermometer in Nanotube Back in the analog age, a thermometer was a simple thing, just a glass tube containing a column of mercury.

These two pressures are expressed in millimeters of mercury (mm Hg) because the original devices that measured blood pressure used a column of mercury.

Perier was to take a barometer up the Puy de Dome and make measurements along the way of the height of the column of mercury.

Arterial pressure is most commonly measured via a sphygmomanometer, which historically used the height of a column of mercury to reflect the circulating pressure.

One atmosphere of pressure will push the column of mercury (Hg) in a mercury barometer to a height of 760 millimeters.

He created the original prototype of his patented device using an old blood pressure cuff, a column of mercury, a pump from a fish tank and a microphone.

Stancari experimented with Guillaume Amontons' air thermometer, where air in the bulb pushes up a column of mercury as it expands due to rising temperature.
