Density of hquids

Liquid sodium alumiaate is available ia steel drums having an approximate capacity of 210 L and bulk shipments are available ia either tank tmcks or railroad tank cars. The density of Hquid sodium alumiaate is usually from 1450 to 1510 kg/m. SoHd products are available ia moisture-proof paper bags or fiber drums containing approximately 23 and 150 kg, respectively. 

Specific gravity (sp gr) is a measure of the relative weight of one Hquid compared to a universaHy familiar Hquid, generaHy water. More speciftcaHy, sp gr is a ratio of the density of a Hquid divided by the density of Hquid water at 16°C (60°F). Specific gravities of selected Hquids are shown in Table 1. 

The density of Hquid carbon monoxide at various temperatures is Hsted in Table 4 (5,7). The density of gaseous carbon monoxide (7) can be calculated direcdy from the equation of state using the compressibihty factor at the temperature and pressure of interest.

The density of a substance is the ratio of its mass to its volume. For example, the density of hquid acetone at 20°C is 0.791 g/cm, so that one cubic centimeter of liquid acetone at 20°C has a mass of 0.791 gram. Density can be thought of as a conversion factor between mass and volume or between mass flow rate and volumetric flow rate. 

Spherical particles 15 nm in diameter and of density 2290 kg/m3 are pressed together to form a pellet. The following equilibrium data were obtained for the sorption of nitrogen at 77 K. Obtain estimates of the surface area of the pellet from the adsorption isotherm and compare the estimates with the geometric surface. The density of hquid nitrogen at 77 K is 808 kg/m3. 

Often this quantity is multiplied by 100 to give the percent relative humidity. Suppose the percent relative humidity is 80.0% at91.4°F (33.0°C) in a house with volume 245 m. Then an air conditioner is mrned on. Due to the condensation of water vapor on the cold coils of the air conditioner, water vapor is also removed from the air as it cools. After the air temperature has reached 77.0°F (25.0°C), the percent relative humidity is measured to be 15.0%. (a) What mass of water has been removed from the air in the house Reminder Take into account the difference in saturated water vapor pressure at the two temperamres.) (b) What volume would this liquid water occupy at 25°C (Density of hquid water at 25.0°C = 0.997 g/cmL)... 

Some gases can be converted to hquids at room temperature by being compressed into a smaller volume, but for each gas, there is a temperature above which the particles are moving too fast to allow a hquid to form no matter how much the gas is compressed. The temperature above which a gas cannot be hquefied is called the critical temperature. The very high pressures that are possible for a gas above its critical temperature allow the formation of gas systems in which the density approaches the densities of hquids. At this high pressure and density, the substance takes on characteristics of both gases and liquids and is called a supercritical fluid. 

The principal experimental method used to measure the density of a solid is determination of the mass of liquid displaced by a known mass of solid. It is essential that the solid have no appreciable solubility in the liquid, that all occluded air be removed from the solid and that the density of the displacement fluid be less than that of the solid lest the solid float. Densities of ciystalline solids also can be determined from the dimensions of the unit cell. Davis and Koch discuss other methods for measuring the density of hquids and solids such as hydrostatic weighing of a buoy and flotation methods. 

Where p is density of hquid manure, g the gravity (9.8 m s ), H the hydrostatic head of hquid manure (m), and Q the volumetric flow rate of liquid manure recirculation (m s ). As concluded by Wu and Chen, the optimal power input in their work is 031SHP. Equation (5) shows the relation between power input of pump to accomplish slurry recirculation and the operation parameters. 

The two walls repel each other when the density of hquid at the walls increases upon approach. If the density decreases, the two surfaces attract each other. To obtain the force per unit area, we need to find out how the density at the walls changes when they come closer.
