The term vacuum is used to e.xpress pressures less than atmospheric pressure (sometimes represented as a negative psi on pressure gauges). Another scale frec]uently used is inches of mercury . The conversion is 14.7 psia = 29.92" Hg. Another scale gaining in popularity is the kilopascal (Kp) scale. 14.7 psia = 100 Kp... [Pg.5]

Note that there are many ways to express vacuum. Simple gauges record vacuum negative psig. Compound gauges record vacuum as a positive psia. The v-t h.-uses inches of mercury in the daily forecast, and millibars ("GOO i ... [Pg.5]

It is the energy in the liquid rec]uired to overcome the friction los.ses from the suction nozzle to the eye of the impeller without causing vaporization. It is a characteristic of the pump and is indicated on the pump s curve. It varies by design, size, and the operating conditions. It is determined by a lift test, producing a negative pressure in inches of mercury and converted into feet of required NPSH. [Pg.13]

Where e, is in units of inches of water per day. Up is the wind speed 2 feet above the ground expressed in miles per day, and e and e, are the saturation vapor pressures at mean air and mean dew-point temperatures, respectively (expressed in inches of mercury). For development of the wind function, an adjustment in the psychrometric constant is generally made to account for the sensible heat conducted... [Pg.548]

Absolute zero pressure is absolute vacuum. This is 0 psia, also known as 29.92 inches of mercury below atmospheric pressure, or 33.931 feet of water below atmospheric, all referenced at sea level,... [Pg.53]

If pressure is expressed as inches of mercury vacuum, the reading of the local barometer (or a reference barometer) is necessary to establish the absolute sucdon pressure, or pressure in the vacuum system. [Pg.348]
