Sprinkle

If the spreading is into a limited surface area, as in a laboratory experiment, the film front rather quickly reaches the boundaries of the trough. The film pressure at this stage is low, and the now essentially uniform film more slowly increases in v to the final equilibrium value. The rate of this second-stage process is mainly determined by the rate of release of material from the source, for example a crystal, and the surface concentration F [46]. Franses and co-workers [47] found that the rate of dissolution of hexadecanol particles sprinkled at the water surface controlled the increase in surface pressure here the slight solubility of hexadecanol in the bulk plays a role. 

Over 50 solved example problems are sprinkled throughout the book. 

The Food, Dmg and Cosmetics Act defines a cosmetic as a substance intended to be mbbed, poured, sprinkled, or sprayed on, introduced into, or otherwise appHed to the human body or any part thereof for cleansing, beautifying, promoting attractiveness, or altering the appearance. A dmg is defined as an article intended for use in the diagnosis, cure, mitigation, treatment, or prevention of disease in humans or other animals, and articles intended to affect the stmcture or any function of the body of humans or other animals. 

Filter Beds. The sprinkling filter beds of sewage plants are composed of closely screened mineral aggregate of 38—64 mm or 51—76 mm that meet a severe soundness test. Much of this requirement is suppHed by dense, fine-grained, hard limestone and dolomite. 

Because dimethyl sulfate looks like water, operations are preferably not performed when water is present, eg, wet floors or rain. Any spills or leaks should not be left unattended they should be contained, and mnoff to sewers should be avoided. Minor spills should be flooded with water to dilute and hydroly2e the dimethyl sulfate. The area should then be covered with a dilute (2—5 wt %) caustic solution or a dilute (2—5 wt %) ammonia solution, or soda ash may be sprinkled over the neat liquid and the mix wetted with a gende spray of water. The neutrafi2ing agent should remain on the affected area for 24 h and then should be washed away. Only personnel wearing protective equipment should perform these operations. The product bulletins should be consulted for procedures to be followed for more severe spills. Concentrated ammonia should not be used with neat dimethyl sulfate because explosions have resulted after their contact (128). 

HBr reacts with metals, producing highly explosive hydrogen gas. If aleak or spill occurs, exposure to the vapors should be avoided. If a high concentration of aqueous acid is accidentally spilled, it should be diluted immediately with water to reduce fuming prior to neutralization. Hydrobromic acid may be neutralized with soda ash or lime sprinkled over the contaminated area. An aqueous solution of sodium hydroxide may also be used to neutralize the diluted acid. 

Initially, tests are run to identify the major eritieal frequeneies of the impeller. Mode shapes are then determined visually at eaeh of the eritieal frequeneies. To obtain these mode visualizations, salt is sprinkled evenly on the dise surfaee. The shaker is maintained at a partieular frequeney, at whieh value a given eritieal frequeney is exeited for a eertain length of time so that the salt partieles display the mode shape. The salt aeeumulates in the nodal regions. Photographs are taken at lower values of these eritieal frequeneies. Photography allows a qualitative identifieation of the appropriate mode shapes eorresponding to eaeh frequeney. Figure 5-27 shows an impeller with the mode shapes.
