The rise of large gas bubbles through tubes filled with viscous liquids

Creator:

Brown, Gary Leigh

Abstract:

An analysis of the velocity and the shape of large gas bubbles rising through tubes filled with viscous liquids is presented. Four tubes, with diameters ranging from 0. 446 inches to 3. 97 inches, and three liquids, with viscosities ranging from one to 200 centipoise, were used in the study....

Deposition characteristics of magnesium silicate and calcium carbonate in cooling tower water

Creator:

Lee, Sai Heep

Abstract:

Deposition characteristics of magnesium silicate and calcium carbonate on a heated surface in cooling tower water using city water as make-up was investigated. Flow velocity, bulk temperature and calcium hardness were maintained constant at 5.3 ft/ sec, 95°F and 150 ppm as CaCO₃ respectively whereas surface temperature varied from 105°F...

Calcium carbonate scaling characteristics of cooling tower water

Creator:

Coates, Kenneth Edwin

Abstract:

Scaling characteristics of calcium carbonate on a heated surface in cooling tower water was investigated. Bulk temperature was maintained constant at 95°F. Flow velocities and surface temperatures ranged from 3 ft/sec to 10.3 ft/sec and from 105°F to 170°F respectively. City water was used as make-up for two different water...
