The most common manometer fluids arc water, alcohol, and mercury. The density of water and alcohol arc quite close to each other, whereas the density of mercury is much higher. Many factors have to be considered when selecting a fluid for a manometer, including... 

Sulphuric acid of density 1300 kg/m3 is flowing through a pipe of 50 mm, internal diameter. A thin-lipped orifice, 10 mm in diameter is fitted in the pipe and the differential pressure shown on a mercury manometer is 0.1 m. Assuming that the leads to the manometer are filled with the acid, calculate (a) the mass flow rate of acid and (b) the approximate drop in pressure caused by the orifice in kN/m2. The coefficient of discharge of the orifice may be taken as 0.61, the density of mercury as 13.550 kg/m3 and the density of the water as OHIO kg/m ... 

Suppose you were marooned on a tropical island and had to use seawater (density 1.10 g-cm 3) to make a primitive barometer. What height would the water reach in your barometer when a mercury barometer would reach 73.5 cm The density of mercury is 13.6 g-cm 3. 

Low-pressure gauges in research laboratories are occasionally calibrated in inches of water (inH20). Given that the density of mercury at 15°C is 13.5 g-cm-3 and the density of water at that temperature is 1.0 g-cm what is the pressure (in Torr) inside a gas cylinder that reads 1.5 inH20 at 15°C ... 

Explain why the density of mercury (13.55 g-cm-3) is significantly higher than that of cadmium (8.65 g-cm-3), whereas the density of cadmium is only slightly greater than that of zinc (7.14 g-cm 3). 

A further rising of the reservoir causes a compression of the gas in the capillary C (closed). Capillary D is open and connected to the vacuum system. The difference Ah between the two mercury heights corresponds to a pressure difference Ap = pg-Ah (Ah in mm gives numerically Ap in torr) p is the density of mercury. If the compression of the gas in B and C is isothermal, we can write ... 

The density of mercury and pure air-free water under a pressure of 101 325 Pa(l atm) is given in units of grams per cubic centimeter (g cm-3). For mercury, the values are based on the density at 20°C being 13.545 884 g cm-3. Water attains its maximum density of 0.999 973 g cm-3 at 3.98°C. For water, the temperature °C) of maximum density at different pressures (p) in atmospheres is given by...

According to Kast and Haid [55] the rate of detonation against the density of mercury fulminate is related as follows ... 

The density of mercury at several selected temperatures is known as follows... 

If a barometer were filled with a liquid of density 1.60 g/ml, what would be the reading when the mercury barometer read 730 torr The density of mercury is 13.56 g/ml. 

H20 are absorbed, and the N2 formed, s collected, n a measuring tube At 730 torr and 22°C, the N2 gas displaces an equal volume of mercury, which is weighed and found to weigh Is 000 g The density of mercury is 13 56 g/ml Calculate the empirical formula of the compound... 

An unknown liquid is used to fill a closed-tube manometer. A system is found to produce a height difference of 4.02 m in this manometer at the same time that a closed-tube mercury manometer attached to the same system gives a displacement of 753.2 mm. What is the density of the unknown liquid The density of mercury is 13.6 g cm 3. 

What is the osmotic pressure of this solution at 20°C Assume that the density of the solution is the same as that of benzene, 0.88 g-cm-3. (b) The freezing point of a different benzene solution was 5.4°C. Determine the osmotic pressure of the solution at 10°C. (c) Determine the height to which osmosis will force the solution in (b) to rise in an arrangement like that shown in Fig. 8.35. The density of mercury is 13.6 g-cm 3. See Exercise 8.120 for more information. 

C. Manometers for High Accuracy Work. For a mercury manometer with one arm evacuated, the pressure is given by P = hdg, where h is the difference in the height of the mercury columns, d is the density of mercury, andg is the acceleration due to gravity. In the old set of pressure units the pressure was reported in mm of Hg. This pressure unit was defined for mercury at 0°C, where its density is 13.5951 g/cnv and the acceleration due to gravity is g0 = 980.665...

Conversion factors for various pressure units and flow units are given in Table VI.1. Table VI.2 lists values of the ratio d,/do (the density of mercury at a temperature t divided by the density of mercury at 0°C) over the temperature range 0-99°C. Capillary depression corrections for mercury in glass tubes are given in Table VI.3. The complete set of corrections for a pressure measurement is made as follows ...
