Eor noncircular apertures, the equivalent hydraulic diameter should be used. Eor crimped metal ribbon elements, the equivalent hydraulic diameter of a right isosceles triangle is 0.83 times the crimp height, and the thickness (width) should be at least 0.5 inches (EISE 1980). 

A further class. Type 4, has been proposed. It is composed of three Cu atoms two of which are strongly coupled, being only 340pm apart. The third Cu atom completes an isosceles triangle, being 390-400 pm from each of the first two, and is normal . 

In the study by Hetsroni et al. (2006b) the test module was made from a squareshaped silicon substrate 15 x 15 mm, 530 pm thick, and utilized a Pyrex cover, 500 pm thick, which served as both an insulator and a transparent cover through which flow in the micro-channels could be observed. The Pyrex cover was anod-ically bonded to the silicon chip, in order to seal the channels. In the silicon substrate parallel micro-channels were etched, the cross-section of each channel was an isosceles triangle. The main parameters that affect the explosive boiling oscillations (EBO) in an individual channel of the heat sink such as hydraulic diameter, mass flux, and heat flux were studied. During EBO the pressure drop oscillations were always accompanied by wall temperature oscillations. The period of these oscillations was very short and the oscillation amplitude increased with an increase in heat input. This type of oscillation was found to occur at low vapor quality. 

In principle, sites a, IT, and c need not be association sites as depicted by Ogston but could be steric sites that form obstructions such that the adsorbed molecule is chirally directed. Only one active site is actually required providing the remaining two sites (protuberances or cavities) are different from each other and from the active site that catalyzes the reaction. They could be identical providing they are not symmetrically oriented with respect to the active site (not an isosceles triangle). These are the basic concepts for a chiral environment on a surface and they lead to the three basic methods for creating chiral surfaces in heterogeneous catalysis.

The flow distribution in a cylindrical vessel has the shape of an isosceles triangle with apex on the axis, thus u = u0(j 3j, /3 = r/R. Find the mean velocity and the mean conversion of a reaction with a power law rate equation. Compare with laminar and uniform flows. 

The size of an equal leg fillet weld is the leg length of the largest inscribed isosceles right triangle (theoretical throat = 0.707 X size). 

In an effort to improve the accuracy of the determination of the end-point, the triangle-programmed titration was devised [97]. The sample with concentration Cx flows at a constant rate of Wj. The titrant is introduced at programmed volume flow-rate Ir, the change in Fr following the pattern of an isosceles triangle (fig. 5.13a). The time of the whole program is 2t, for tr, Ir =(2r—r)n n and t are constants. The maximum titrant mass flow should exceed the sample mass flow (= c w ). Two connected titration curves are obtained (fig. 5.13h), the time elapsed between the two equivalence points for the titration reaction... 

The two dinuclear units are linked by /13-oxo and /i-carboxylato groups. The third position in the "coordination sphere" of the /13-oxo groups is occupied by an unusual 5 coordinate, trigonal bipyramidal iron atom. This is the only case known so far in oxo-iron aggregates. The /13-oxo bridge is of type B since the surrounding metal atoms form an isosceles triangle.
