41. Hence, the residence time of particles in the rotating screen can be determined from the equation below: 42. The long residence time of plutonium in the body is partly explained by its poor solubility in water. 43. The formation rate is primarily a function of temperature and the residence time of nitrogen at that temperature. 44. The kiln is equipped with a variable speed drive, which allows varying rotation speeds and material residence time . 45. The amount of residence time required to achieve outgassing is directly dependent on the temperature of the environment. 46. Even though residence time and temperature are carefully controlled, it produces significant quantities of chlorinated hydrocarbon side products. 47. The hydraulic residence time of Harveys Lake is 1116 days . Visibility in the lake is typically approximately. 48. Here the residence time is being used to determine the changing concentration of a contaminant in a system. 49. DAF systems can be categorized as circular ( more efficient ) and rectangular ( more residence time ). 50. Fiber growth in several centimeters was achieved in just 10 minutes with a gas residence time of 20 seconds.
