Some aspects of what is described here relate to analyzing a well cement slurry. In some aspects, a well cement slurry is mixed in a mixer under a plurality of conditions. The plurality of conditions correspond to a plurality of distinct Reynolds number values for the well cement slurry in the mixer. Power number values associated with mixing the well cement slurry in the mixer under the plurality of conditions are identified. Each power number value is based on an amount of energy used to mix the well cement slurry under a respective one of the plurality of conditions. Values for parameters of a functional relationship between power number and Reynolds number are identified based on the power number values and the Reynolds number values for the plurality of conditions.

A breaking strength tester includes: a tubular pressure container having opened both ends to house a part of a pillar-shaped honeycomb structure including a partition walls and a circumferential wall; a tubular pressurization elastic body disposed to surround an entire circumference of a pressurized portion having a length equal to or less than of a length in an axial direction of the circumferential wall; a partial pressurization unit which elastically deforms the pressurization elastic body and applies uniform pressure to the entire circumference of the circumferential wall of the pressurized portion of the honeycomb structure housed in the pressure container up to pressure test strength; and a pressure measurement unit which measures a value of the uniform pressure applied to the circumferential wall by the pressurization elastic body.

A method for quantifying carbon in carbides that allows highly precise and simple quantification of carbon in carbides. The method for quantifying carbon in the carbides includes a combustion process in which the carbides are heated together with a composite member in the presence of oxygen to oxidize the carbon in the carbides to carbon monoxide and/or carbon dioxide, and a quantification process of quantifying the carbon monoxide and/or the carbon dioxide. The composite member includes two or more metal members that have main components that are different from each other.

A method of testing for impurities includes directing an x-ray source toward a surface at an angle relative to the plane of the surface, the surface defined by a ceramic coating over a crystalline substrate; detecting x-ray fluorescent radiation emitted from the ceramic coating at an angle different from the angle and its supplementary angle; and comparing characteristics of the detected x-ray fluorescent radiation to characteristics associated with impurities.

An investment casting shell substrate sensor method and apparatus comprising a hollow probe 10 having an aperture 30, the aperture 30 covered by a water proof breathable membrane (WPBM) 20 that is constructed and arranged to repel liquid from entering the aperture 30, while remaining permeable so as to allow vapor and air to pass through the aperture 30, thereby creating a liquid free internal void 50 within the hollow probe 10 that receives a sensor 40 for measuring the conditions (i.e. temperature and humidity) within the internal void 50, which are accurately indicative of the conditions at the shell substrate at the aperture 30 location. The disclosed sensor assembly provides target specific information at selected substrates within the shell real time, during the shell building process.
