The purpose of this study was to review all material relevant to the design, construction, and operation of a large floating columnar platform made of ferroconcrete. Existing platforms, motion analysis, anchoring, powering, assembly and ferroconcrete are discussed. The study indicates that ferroconcrete platforms can be built and that electric power generation sites may be the first application of the idea.

A practical technique was developed for in vivo determinations of the mechanical properties of canine left ventricle. A “quick stretch” was accomplished by rapid injection of isotonic saline into the ventricle during isovolumetric systole. The experimental pressure-volume data and a stress-strain analysis of the left ventricle as a thick-walled sphere permitted determination of the effective elastic modulus as a function of the mean circumferential stress. The elastic modulus E was found to be a linear function of the mean tangential stress σ throughout the isovolumetric systolic period; the slope (K, modulus of stiffness) of the Eversus σ curve was 18.8 with a standard deviation of 0.9.

A visualization study of the flow through a three ft dia model of a four bladed inducer, which is operated in air at a flow coefficient of 0.065, is reported in this paper. The flow near the blade surfaces, inside the rotating passages, downstream and upstream of the inducer is visualized by means of smoke, tufts, ammonia filament, and lampblack techniques. Flow is found to be highly three dimensional, with appreciable radial velocity throughout the entire passage. The secondary flows observed near the hub and annulus walls agree with qualitative predictions obtained from the inviscid secondary flow theory.

This paper describes an experimental investigation of two-phase, air-water nozzle flows including critical or choked flow. Five different nozzle geometries were used. The nozzles exhausted to atmospheric pressure from stagnation pressures of 16 to 55 psia. The quality (mass fraction of air flowing) ranged from 2 to 35 percent. A feature of the study was the injection system which was designed to minimize the entrainment of liquid into the gas phase. The data were found to be described within about 10 percent by modifying separated flow theory by a simple “blockage factor” correlation.

The author reviews methods of calibrating low-differential (25–300 in. H2 O) D.P. transmitters at high (up to 3000 psig) static pressure. Various test methods are described along with discussion of their merits. Included are use of one or more deadweight testers (gas or liquid) and use of a high-pressure mercury manometer as a standard. Five D.P. transmitters of different construction are tested and their static span-shift performance reported.
