Strength pressure

Elastic Strength Pressure (ESP). Computed true internal gas pressure in a gun at any given cross section thereof that will stress the metal at the inner layer of the wall at that section tangentially up to the max elastic limit of the metal from which the inner layer is made. Normally required to be at least 1.5 times the computed max pressure...

Figure 6.6 ULtrafiLtration separates molecules based on size and shape, (a) Diagrammatic representation of a typical laboratory-scale ultrafiltration system. The sample (e.g. crude protein solution) is placed in the ultrafiltration chamber, where it sits directly above the ultrafilter membrane. The membrane, in turn, sits on a macroporous support to provide it with mechanical strength. Pressure is then applied (usually in the form of an inert gas), as shown. Molecules larger than the pore diameter (e.g. large proteins) are retained on the upstream side of the ultrafilter membrane. However, smaller molecules (particularly water molecules) are easily forced through the pores, thus effectively concentrating the protein solution (see also (b)). Membranes that display different pore sizes, i.e. have different molecular mass cut-off points, can be manufactured, (c) Photographic representation of an industrial-scale ultrafiltration system (photograph courtesy of Elga Ltd, UK)...

When the best catalyst has been chosen and found to fulfil the requirements with respect to activity, strength, pressure drop, production and profitability, a procedure must be developed for calculation of the catalyst volume required to obtain a given SO2 conversion in an industrial reactor. In its simplest form, the calculation basis can be a table or an expression for space velocity (NHSV) as a function of feed gas properties and final conversion. A more detailed approach is used for design of catalytic reactors at Haldor Topsoe, where a rate expression of the form... 

Other interesting properties of (bio)chemical sensors are related to their effectiveness for solving real analytical problems. First, these analytical devices should be easy to construct, operate and preserve. Ruggedness, defined here as the confidence that small variations in the experimental conditions (pH, temperature, ionic strength, pressure) will not alter the sensor functioning or response, is very important. A low cost is also desirable, particularly with single-use (bio)chemical sensors. 

Detonation Processes Properties of Explosive Affecting Them. This is a very broad subject and might include Chapman-Jouguet parameters (See Table under "Detonation, Chapman-Jouguet Parameters in ), thermohydrodynamic properties, brisance, density, power or strength, pressure of detonation, temperature of detonation, sensitivity to impact, sensitivity to initiation and detonation velocity...

Selective. Sensors should have minimum interference from nonanalyte parameters such as temperature, ionic strength, pressure, and other chemical species not being measured. One route to successful sensor design will rely on the identification of appropriate and selective recognition chemistry. 

Agglomerate porosity and density. This is closely related to product strength. Pressure methods are well suited to control of porosity which may be needed in some applications.

Apart from its mechanical strength, pressure resistance and chemical inertness, high demands are put on the geometric construction of the flow lines in such valves, as discussed below. Usually all parts of sampling valves are made of 316 stainless steel. Carpenter 30 alloy or ceramic materials of extreme hardness such as an alumina ceramic. The sealing parts consist in most instances of PTFE or PTFE-filled materials such as Rulon. These materials commonly guarantee high mechanical and chemical resistance.

Automatic. Self-acting, operating by its own mechanism when actuated by some impersonal influence, as for example, a change in current strength, pressure, temperature, or mechanical configuration.
