ASME 62-WA-328 . - Hydraulic fluids Air bubbles in oil--their effect? on viscosity and compressibility,? A T J Hayward, National Engineer-7 ing Laboratory, Glasgow In this study, bubbly oil is defined as oil containing bubbles that are sep-' arated by relatively thick films, as op-' posed to foam. Viscosity tests de- -in scribed show that small bubbles (0.010 to 0.020-in. dia) have a; straight-line effect on viscosity up to^ a bubble content of 25%. Compression tests show n values -,r slightly under unity--less than iso- * thermal. This is due to loss of air.' to the solution, giving an apparent* deviation from the true law of com*? pression. Future work will increase?-' test accuracy. NCIH T Dynamic fluid properties, R L-' Leslie, Vickers, Inc New testing and instrumentation tech- \ niques have made possible a rigorous ' re-examination of many hydraulic fluids. Compressibility is usually ex*^pressed in a reciprocal form--bulk-Si modulus. But there are several ac cepted bulk moduli for you to keep '4 straight. Pressure-viscosity relationships are; covered. Effects of shear rate on vis cosity have been complicated by: popular addition of polmeric thick-? ening agents. And the non-Newtonial characteristics of water-in-oil emul-. sion fire-resistant fluids have further focused interest on the effect of shear rate. Temporary increase and per*, manent loss of viscosity are explained Viscoelastic properties of hydraulic fluids are attracting attention. We may no longer safely assume that a fluid will start to flow as soon as a force is applied.

"Belay the soft stuff, you bewitch-, ing chickadees!", he roared good- naturedly. as he handed them the package. "Where's your momma?" "Voila! voila!" Madame Rose was all smiles as she emerged from the kitchen where she was planning her day's menus. "Ah, Monsieur Marma- duc, we haven't seen you for so long. We are missing you ... oh no no ; again a package ... no you should not, but sit down and have cafe- cognac, while I fix your breakfast," she effervesced. "Yes," chimed in Simone, "but first we must show him our new farm." "Our brand-new chicken farm," Claudine explained as they led Marmy, one pulling at each arm, to the back yard, where hundreds of white Leghorns were enjoying their morning meal in the shadow of the small diesel plant. "We started our new business with the money you sent us for a New Year's present, M'sieu Marma- duc, and it's' marching very well," blurted Simone. ; "That's more than Louis' diesel plant is doing, I'll bet," Marmy said almost to himself as his keen eyes and ears quickly took in several telltale trouble signs about the plant. "Yes," he rumbled to the girls, "I hope this chicken business pays off. But don't let it keep you from school," he warned. "Takes a lot of studying to make you interesting enough for a smart young millionaire to marry." "Oh, yes, we know," Simone gig gled, "but we are studying." 1 "Yes, we want to become smart like you, M'sieu Marmaduc," Clau* dine added, smiling coquettish!/: Marmy glanced at her with approval. Yes, this one especially has enough feminine charm to make a king giv| up his throne, he mused, even if she couldn't read or write. "Well, let's barge back to the gah ley," he declared, "and see how you* momma is coming with the chow." ? Madame Rose was indeed doin very well with the vittles.

Stone & Webster Engineering^ Corp and Westinghouse Electricmade the preliminary design of the plant (artist's sketch is shown below). The Ravenswood reactor is to be an advanced version of Con Edison's Indian Point reactor. The nuclear process will account for about twothirds of total energy output of the system; nuclear fuel will consist of 156 elements of a low-enriched (3.5%) uranium oxide. Five primary coolant loops of pressurized water will operate at 2035 psia. Coolant temperature will rise from 543 F at inlet to 588 F at out let, and will produce steam at 685 psig and 503 F in the boilers. That steam will be superheated to 1000 F^ in two oil-fired superheaters having a total capacity of 8.8 million lb per hr, and will reach the 1800-rpm tur-\ bine at 560 psig. * At reduced electric capacity, using! isolating steam reboilers, some 2-mil-; lion lb of steam per hr will be avail-? able for district heating.
