Specific Volume of Mercury

The calculated void fraction based on the specific volume of mercury intruded is too high for the sand and much too low for the Cas (PO4 >2. Therefore, it is reasonable to assume that the sample is FCC with an e equal to 0.39. The particle density equals ... 

From Mercury—Density and Thermal Expansion at Atmospheric Pressure and Temperatures from 0 to. 350 C, Tables of Standard Handbook Data, Standartov, Moscow, 1978. The density values obtainable from those cited for the specific volume of the saturated liquid in the Thermodynamic Properties subsection show minor differences. No attempt was made to adjust either set. 

Fig. 10.9 Specific conductivity of mercury at 1550°C as a function of density p (Hensel and Frank 1968). V is the volume and V0 that at normal temperature and pressure.

At 60°F and atmospheric pressure (30 inches of mercury), the specific volume of oxygen is 11.819 cubic feel per pound. Therefore, I mole of oxygen has a volume of 32 x 11.819 = 378.21 cubic feci. Similarly, at 60°F and atmospheric pressure, the specific volume of hydrogen is... 

Example 1.2 Table 1.3 lists the specific volumes of water, mercury, hydrogen at l(atm), and hydrogen at lOO(atm) for a number of temperatures on the International Practical Temperature Scale. Assume that each substance is the fluid in a thermometer, calibrated at the ice and steam points as suggested at the beginning of this section. To determine how good these thermometers are, calculate what each reads at the true temperatures for which data are given. 

Fig. 8.5 Relations between porosities (volume percentages) and water/ccmcnt ratio for mature Portland cement pastes. The experimental data are for pastes at least 8 months old, and the calculated curves relate to a typical cement aged 18 months. Open symbols total water porosities. Filled or half-filled symbols mercury porosities. Curve A total water porosity. Curve B free water porosity. Curve C capillary porosity. References to data O (P20) O (S77) A (F33) V (M68) (S78) (F34) 9 (019) (M68) (D3I) 3 (H4I). In the last two cases, porosities by volume were estimated from data referred in the original sources to masses of dried paste, assuming the tatter to have contained 0.23 kg of water per kg of cement having a specific volume of 3.17 x 10 m kg h...

The product of PV for a low-density gas is said to be a thermometric property in that to each value of FV there corresponds only a single value of temperature. The ideal gas thermometer is not convenient to use. however, because of both its mechanical construction (see Fig. 1.4-3) and the manipulation required to make a measurement. Therefore, common thermometers make use of thermometric properties of other materials—for example, the single-valued relation between temperature and the specific volume of liquid mercury (Problem 1.2) or the electrical resistance of platinum wire. There are two steps in the construction of thermometers based on these other thermometric propenies first, fabrication of the device, such as sealing liquid mercury in an otherwise evacuated tube and second, the calibration of the thermometric indi-...
