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...

Effects of water quality and surface temperature on the scaling characteristics of cooling tower water

Creator:: Lahm, Lawrence
Abstract:: The fouling of cooling tower water was investigated as a function of heater surface temperature and water quality. In particular, the effects on fouling of the addition of calcium in excess of the amounts required for saturation were examined. First, the average bulk water temperature was 97 ± 1 degree...

Turbulent mixing across adjacent subchannels in packed rod bundles using conductivity measurement

Creator:: Chan, Pui Yuen
Abstract:: Turbulent mixing across adjacent subchannels in packed rod bundles was studied using conductivity measurement and sodium chloride solution as the tracer. Single phase water was the fluid investigated. The packed rod bundles were seven stainless steel tubes, 1.905 cm in diameter and 152.4 cm long, arranged in hexagonal close-packed configuration...

Friction losses for water flowing in non-circular ducts

Creator:: Mohandes, Abdolhosein
Abstract:: Friction factors were measured for water flowing in ducts made up of two rods held between two flat plates. Three rod diameters of 0.50, 1.00 and 1.50 inches were used. The spacings between rods varied from 0.0 to 0.32 inch. It was found that the concept of hydraulic diameter was...

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...

Motion picture study of a vertical climbing film in an annular duct

Creator:: Scott, Bruce Douglas
Abstract:: This paper describes a study of two-phase gas-liquid vertical annular climbing film flow. Using a high speed Fastax movie camera, motion was slowed sufficiently to facilitate detailed analysis of the climbing film structure, based on single frame projections. The dynamic characteristics of the liquid film could likewise be obtained, though...
