Pressure and Fluid Flow

1/53 40 "The Kidney." by Homer W. Smith. How the kidney regulates volume and composition of body fluids and how it filters the blood.
8/54 24 See category 6.
9/55 96 "The Circulation of the Oceans." Munk; a study of the complex patterns in which ocean waters flow - some of the physics is applicable.
10/55 124 "The Amateur Scientist." A study of the dynamics of airflow and waterflow with simple apparatus.
4/58 36 "Cells at High Pressure." Marsland; It is well known that temperature affects cellular processes. What about pressure?
5/58 125 "Body Water." Wolf; it diffuses freely through the tissues, but its total amount is closely regulated.
6/58 30 "Superfluidity." Lifshitz; A USSR physicist tells what has been learned about this strange phenomena.
1/59 54 "The Microcirculation of the Blood." The mechanisms that regulate blood flow.
8/59 110 "Glaucoma." Fluid pressure in the eye causing blindness.
12/59 122 "The Flow of Matter." The discovery that everything flows, including solids.
1/60 138 See category 4.
7/60 118 "The Buoyancy of Marine Animals." Denton; Different methods sea creatures use to keep them from sinking, i.e. constant swimming or flotation chambers.
4/61 134 "Ultrahigh-Speed Rotation." by Jesse W. Beams. Centrifuges have now been made that can spin a rotor 1.5 million times per second.
8/62 101 "Pumps in the Living Cell." Soloman; the localization of the sodium pump in Necturus.
3/65 104 "Computer Experiments in Fluid Dynamics." F. H. Harlow and J. E. Fromm.
8/65 70 "Density Gradients." Gerald Oster. Separation and identification technique and application to biologic research.
8/66 49 See category 6.
1/67 62 "Pipelines." Jensen and Ellis; discussion of the transportation of oil and gas via pipelines and how the liquids flow through the pipes.
1/68 86 "The Venous System." Wood; deals with pressure and fluid flow dynamics of the cardiovascular system.
1/69 52 "Weather Satellites: II." A. W. Johnson; neat pictures showing atmospheric flows.
1/70 114 "Models of Oceanic Circulation." Baker; The great oceanic currents are studied by means of analogues at laboratory scale.
7/70 72 "Negative Viscosity." Starr and Gaut. Viscosity is associated with decreasing shear, but in many cases shear increases.
1/71 32 "The Global Circulation of Atmospheric Pollutants." Reginald E.Newell; how wind and temperature patterns are studied in order to observe what effect changes in the atmosphere caused by man have on the earth's surface.
11/74 96 See Category 6.
11/75 81 "Unusual Mechanisms for Generation of Lift in Flying Animals." Torkel Weis-Fogh; explanation of "clap flying" and "flip" methods of flying; non-steady aerodynamics, physics involved in hovering.
5/76 ? "Stephen Hals." The measurer of the flow of water and sap in plants and thus founder of plant physiology.
6/76 28 "An Electron-Hole Liquid." Thomas; the carrier of an electric charge inside a crystal may have the properties of a fluid. This fluid is a quantum mechanical liquid composed of electrons and holes.
5/78 162 "What Plumes of Smoke Tell About the Structure of the Atmosphere." J. Walker (Amateur Scientist).
8/78 128 "Organisms that Capture Currents." S. Vogel; a variety of examples of species that take advantage of aerodynamics or hydrodynamics.
11/78 186 "Serious Fun with Polyox, Silly Putty, Slime and other non-Newtonian Fluids." (Amateur Scientist) J. Walker.
1/79 128 "The Head of the Sperm Whale." Clarke; The whale uses the oil-filled spermaceti organ to maintain neutral buoyancy.
4/79 162 "Ink-Jet Printing." L. Kuhn and R. A. Meyers; ink drops form in flight from a small nozzle; electrostatic charges are used to steer them in flight, like an oscilloscope steers its electron beam; used in computer output terminals. A closely related technology is used in automatic cell sorters.
4/79 180 "More on Boomerangs, including their connection with the Dimpled Golf Ball." (Amateur Scientist) J. Walker; an interesting application of aerodynamics.
12/79 66 (See Category 6)
7/80 134 "The Screw Propeller." E. Eugene Larrabee. The propellers of Queen Elizabeth 2 and Gossamer Albatross are designed on the same principles.
10/80 190 "The Buoyancy of the Chambered Nautilus." Peter Ward, Lewis Greenwald and Olive E. Greenwald. How does the animal keep the chambers from flooding?
1/81 124 "Gels." Toyoichi Tanaka. What are the forces that enable a polymer to form a state of matter between a liquid and a solid?
4/81 176 "The charm of hydraulic jumps, starting with those observed in the kitchen sink." Jearl Walker (Amateur Scientist).
5/81 118 (See Category 2)
9/81 216 "Why to honey and syrup form a coil when they are poured." Jearl Walker (Amateur Scientist).
3/82 60 "Rings of the Gulf Stream." Peter H. Wiebe; turbulent flow on a grand scale.
