If using a water manometer to measure millimeters of water the reference pressure ( P _ { 0 } ) may be entered as 10333 mm H _ 20.
42.
:: ( Expanding on trap of your toilet bowl acts as a manometer between the air pressure inside your house and the air pressure in the plumbing vent stack.
43.
Their almost concurrently invented devices consisted of a narrow armlet to occlude the brachial artery, a small bicycle-type metal pump and a metal manometer graduated in mmHg.
44.
Also there is the Knudsen equation; two instruments, the Knudsen absolute manometer and Knudsen gauge; and one gas pump that operates without moving parts, the Knudsen pump.
45.
But now, he added, " for the first time in 100 years we are faced with some places not having mercury manometers available for blood pressure measurements ."
46.
The pressure of a moving fluid can be measured using a Pitot tube, or one of its variations such as a Kiel probe or Cobra probe, connected to a manometer.
47.
Traditionally, blood pressure is measured non-invasively using a mercury manometer because these gauges are dependent upon only gravity, thus inherently more accurate than alternative types of pressure gauges.
48.
Krebs had earlier suggested to Warburg while they worked together in Germany that using manometer it could be possible to detect the oxygen consumption and identify the chemical reaction in glucose metabolism.
49.
A second measurement tool was an alcohol-filled micro-manometer connected to a Pitot tube placed at a 90 & ndash; degree angle to the airflow in the tunnel.
50.
When the wind whips across the vent stack, the venturi effect lowers the pressure in the stack and the water in the toilet-bowl manometer shifts towards the vent stack.
