Density glasses

Calculate the concentration at which the rate of deposition of particles per unit area will be a maximum, and determine this maximum flux for 0.1 mm spheres of glass (density 2600 kg/m3) settling in water (density 1000 kg/m3, viscosity 1 mNs/m2). 

Colorless oily hquid fumes in air etches glass density 2.666 g/ml at 0°C hods at 60.4°C vapor pressure 100 torr at 13.2°C sohdilies at -8.5°C decomposes in water soluble in alcohol, ether, benzene and ammonia solution. 

In the manner described in the preceding exercise, prepare several tubes half filled with a gel obtained by mixing equal parts of water glass (density, 1.06) and acetic acid (0.5 normal) and with the addition of enough potassium chromate to make the solution 0.1 normal with respect to the latter salt. The chromate should be added to the water glass before the addition of the acetic acid. 

A "Cartesian diver is a hollow sealed bulb made of thin glass, such that the overall density is just a little less than 1 g/ml As a consequence, it floats in water If pressure is applied to the gas over the water in which the bulb floats, the bulb collapses a little and then sinks When the pressure is released, it expands and floats again A glass (density = 2 20 g/ml) sphere made on this principle weighs 3 25 g...

One thousand grams of hydrated sodium tungstate is dissolved in 2000 ml. of water. To this solution is added 75 g. of a solution of water glass (density 1.375). The mixture is stirred briskly with a motor stirrer and heated to boiling while 600 ml. of hydrochloric acid (density 1.18) is added a drop at a time from a separatory funnel. This operation takes about 90 minutes. The slight precipitate of silicic acid is filtered off, and the mixture cooled. Four hundred ml. more of the concentrated hydrochloric acid is added, and the solution cooled again. This solution...

The glass density, specific heat, and thermal conductivity were assumed to be constant since they do not vary much within tiie gob forming prxx ss in s study. The density, specific heat and thermal conductivity of the plunger and tube were also specified as constant values.
