"The writer presents a considerable, up to date assessment of the verification and validation process…" (Computer journal, November 2004) "The unifying dialogue at the formal research and verification tools are in particular invaluable and enlightening, either for graduate scholars and researchers. " (International magazine of basic structures, December 2003) the 1st publication to supply a accomplished review of the topic instead of a suite of papers.

Frequency Selective Surfaces: Theory and Design

". .. Ben has been the world-wide guru of this know-how, offering help to purposes of all kinds. His genius lies in dealing with the tremendous advanced arithmetic, whereas even as seeing the sensible concerns taken with making use of the implications. As this publication essentially exhibits, Ben is ready to relate to newcomers attracted to utilizing frequency selective surfaces and to give an explanation for technical info in an comprehensible manner, liberally spiced along with his exact model of humor.

Example text

It takes a force to move the fluid against friction, in the same way that a force is required to lift a weight. The force is exerted in the same direction as the moving liquid and energy is expended. In the same way that head was calculated to  Copyright Fluide Design Inc. 32 lift a certain weight, the friction head is calculated with the force required to overcome friction times the displacement (pipe length) divided by the weight of fluid displaced. These calculations have been done for us and you can find the values for friction head loss in Table 1.

The liquid by being pulled downward by gravity creates a low pressure under our fingertip. The liquid is maintained in balance because the low pressure and the weight of the liquid is exactly balanced by the force of atmospheric pressure that is directed upwards. The same phenomenon occurs in the pump suction which is pulling up liquid from a low source. Like for the straw the pressure close to the pump suction connection must be low for the liquid to be supported. Figure 38 Low pressure at the pump suction is present when the liquid surface is below the pump.

In an industrial setting, the flow rate will often depend on the production level of the plant. 3 L/s) to fill a tank in a reasonable amount of time or the flow rate may depend on the interaction between processes. 2. Determine the static head This a matter of taking measurements of the height between the suction tank fluid surface and the discharge pipe end height or the discharge tank fluid surface elevation. 3. Determine the friction head The friction head depends on the flow rate, the pipe size and the pipe length.
