An exercise in determining a primary standard for hydraulic fluid volume flow rate. Technical Education is a bimonthly supplement to Industrial Arts and Vocational Education. (Editor/GB)

Describes computer assisted learning (CAL) packages written in FORTRAN IV and developed for use in a degree course in civil engineering dealing with hydraulics and structures. All are used in the interactive mode through a terminal with a keyboard and visual display unit. (Author/CMV)

The rate training manual and nonresident career course presents materials for individualized study that will assist Aviation Structural Mechanics in Hydraulics (AMH) in meeting the occupational requirements of their rating. The study materials seek to improve job skills among Navy petty officers in conjunction with their on-the-job training as…

A review of a few of the year's highlights. (BB)

Capillary and gravity water waves are related to the position, wavelength, and velocity of an object in flowing water. Water patterns are presented for ships and the whirling beetle with an explanation of how the design affects the objects velocity and the observed water wavelengths. (DS)

Describes three student experiments in magnetohydrodynamics (MHD). In these experiments, it was found that the electrical conductivity of the local water supply was sufficient to demonstrate effectively some of the features of MHD flowmeters, generators, and pumps. (LC)

Describes an apparatus designed to demonstrate vortical flow of a fluid. The apparatus consists of a transparent acrylic cylinder, with a drain hole, and mounted so that it can be rotated about its axis at speeds up to 1000 rpm. Experimental observations with water as the fluid under study are reported. (LC)

"Impact" is possibly the most frequently evaluated construct associated with any kind of technological diffusion or adoption within educational settings. Seemingly endless research projects are funded to measure it and to validate the educational value we have become adept at inscribing into practically all novel technologies brought to…

Subjects covered in this text are controlling the hydroelectric generator, generator excitation, basic principles of direct current generation, direction of current flow, basic alternating current generator, alternating and direct current voltage outputs, converting alternating current to direct current, review of the basic generator and…

Presented is a method to aid in determining downstream sewer flow capability and of characterizing sewer systems using data processing methods and a Texas Instruments SR-52. (MR)

Describes experiments using fluidyne engines. These engines (which have liquid pistons), started by external heat sources, are used primarily for pumping water. Examples of various engines built from U-shaped tubes or from coiled tubes in fruit jars are provided. (DH)

Using syringes, a hydraulic press was constructed and mechanical advantage and efficiency were calculated. (CP)

Probability-based inference in complex networks of interdependent variables is an active topic in statistical research, spurred by such diverse applications as forecasting, pedigree analysis, troubleshooting, and medical diagnosis. This paper concerns the role of Bayesian inference networks for updating student models in intelligent tutoring…

This document contains teacher's materials for a course on becoming an automotive brakes specialist, based on the National Institute of Automotive Service Excellence task lists. The course consists of three instructional units: service brake hydraulic system and wheel bearings, service drum brakes, and service disc brakes. Depending on the…
