Discussion: “Large Water-Level Displacements in the Simple Surge Tank” (Marris, A. W., 1959, ASME J. Basic Eng., 81, pp. 446–452)

Analysis and Design of a Simple Surge Tank (RESEARCH NOTE)

In a hydroelectric power plant or in a pumping station in order to avoid sudden large increase of pressure due to instantaneous valve closure sometimes a surge tank is installed. The height of surge tank is designed by the highest possible water level during the operation. The theoretical treatment of oscillation in a surge tank is difficult because of the non-linearity of friction term in the ...

Closure to “Discussion of ‘Factors of Safety for Richardson Extrapolation’ ” (2011, ASME J. Fluids Eng., 133, p. 115501)

The Technical Brief by Roache [1] presents ten items of discussion of our factor of safety (FS) method for solution verification [2]. Our responses are listed below item-by-item using the same numbering as Roache. The nomenclature mostly follows our own and not Roache’s such as pRE for the order of accuracy calculated using the Richardson Extrapolation as opposed to the observed order of conver...

The reliability of the narrative of the Biblical Exodus has been subject of heated debate for decades. Recent archaeological studies seem to provide new insight of the exodus path, and although with a still controversial chronology, the effects of the Minoan Santorini eruption have been proposed as a likely explanation of the biblical plagues. Particularly, it has been suggested that flooding b...

Trivelpiece A W & Gould R W. Space charge waves in cylindrical plasma columns. J. Appl. Phys. 30:1784-93, 1959

“This paper had its origins in a summer of 1956 project to build 1,420 mc low noise traveling wave tubes for use as preamplifiers in the Caltech radio telescope. The tubes that I built had measured noise figures that were much worse than the predicted theoretical minimum of six db. I used the standard low noise tube design formulae, which had been previously demonstrated to result in tubes that...
