Water Content Determination by Karl Fischer ...
Water content can be determined by any one of the following procedures: Loss on drying, for drugs containing no constituents other than water volatile at 105°C; Water content by Karl Fischer (Titrimetric) Mix and accurately weigh the substance to be tested, and, unless otherwise directed in the individual monograph, conduct the determination on 1 to 2 g.
12 LABORATORY SAMPLE PREPARATION
Decreases in water content are sometimes observed while grinding solids containing essential water in the form of hydrates, likely as a result of localized heating. (See Section 12.3.1.2 for a discussion of the types of moisture present in solid samples.) Moisture loss is also observed when samples containing occluded water are ground and crushed.

Studies of spheres directed at high speed into water (Marston et al., 2012) show that wettability is a key factor in determining cavity formation (Duclaux et al., 2007). For spheres with hydrophilic surfaces, water wets the sphere surface to some distance above the average water level as the sphere enters.

The Top Advantages and Disadvantages of Carbide Cutting ...
High-speed tools may not cost much but have a poor wear resistance than carbide tools. The cutting edge of HSS might be sharper, but they need replacement in fewer cycles as they can just be sharpened fewer times before it acts on the strength of the device. The tool will not come to use on some particular tough alloys.
