An Analytical Procedure of Calibration for the Pulsed Ultrasonic Doppler Flow Meter
(The American Society of Mechanical Engineers (ASME), 1974)The use of Doppler ultrasonics provides one of the few, if not the only, methods of noninvasive measurement of blood flow and velocity in the body. In terms of overall accuracy the pulsed ... -
A Comparison Between Orifice and Flow Nozzle Laboratory Data and Published Coefficients
(The American Society of Mechanical Engineers (ASME), 1974)Prediction of orifice and flow nozzle coefficients from their dimensions is a matter of major concern. In the mid 1930’s, laboratory flow coefficient data were obtained for flange top orifices ... -
Improved Expansion Factors for Nozzles, Orifices, and Variable-Area Meters
(The American Society of Mechanical Engineers (ASME), 1974)An explicit equation is developed for calculating jet area increase due to compressibility when the incompressible coefficient is known. If the latter is dependent on Reynolds number, Y must ... -
Metering Performance Investigation and Substantiation of the “Universal Venturi Tube” (U.V.T.): Part 2—Installation Effect, Compressible Flow, and Head Loss

Metering Performance Investigation and Substantiation of the “Universal Venturi Tube” (U.V.T.): Part 1—Hydraulic Shape and Discharge Coefficient
(The American Society of Mechanical Engineers (ASME), 1974)The UVT provides Classical Venturi tube type metering performance with less than half the laying length, no annular chambers, and about half the permanent head loss. Data presented reveal the ... -
The Determination of Wall Friction for Vertical and Horizontal Two-Phase Bubbly Flows
(The American Society of Mechanical Engineers (ASME), 1974)The one-dimensional momentum equation without slip is applied to the bubbly flow of air-water mixtures in pipes for Reynolds numbers in excess of 105 . The equation is integrated along the ... -
On a Test of the Resonance Hypothesis
(The American Society of Mechanical Engineers (ASME), 1974)This note presents results of an experimental test of van der Hegge Zijnen’s resonance hypothesis. Near wake turbulence spectra obtained over a range of stream turbulence intensities and integral ... -
A Note on Several Theories of Turbulence in a Uniform Shear Flow
(The American Society of Mechanical Engineers (ASME), 1974)Several theories for the development of turbulence in a uniform shear flow are compared with experiments. Greatest success is found with theories which model the Reynolds stress equations. ... -
Laterally Integrated Numerical Water Quality Model for an Estuary
(The American Society of Mechanical Engineers (ASME), 1974)The development of a two-dimensional, laterally integrated, estuarine, numerical water quality model is presented. The model is then applied to Narragansett Bay’s D.O.-B.O.D. system and shows good ... -
Interfacial Shear in Two-Phase Wavy Flow in Closed Horizontal Channels
(The American Society of Mechanical Engineers (ASME), 1974)The interfacial shear stress for air flowing over a wavy water surface was determined experimentally in a closed horizontal channel by measuring the pressure drop and the structure of the water ... -
A Method of Measuring Three-Dimensional Rotating Wakes Behind Turbomachinery Rotors
(The American Society of Mechanical Engineers (ASME), 1974)A method of measuring the mean velocities and turbulence intensities in a rotating wake behind a turbomachinery rotor is developed. The method utilizes three stationary hot wires located in ... -
Discharge Coefficient Correlations for Circular-Arc Venturi Flowmeters at Critical (Sonic) Flow
(The American Society of Mechanical Engineers (ASME), 1974)Data are presented which tend to verify the theoretically predicted discharge coefficients for circular-arc venturi flow meters operating in the critical flow regime (sonic) at throat Reynolds ... -

Instabilities of a Spatial System of Articulated Pipes Conveying Fluid
(The American Society of Mechanical Engineers (ASME), 1974)A spatial system of two articulated pipes conveying fluid is examined analytically and experimentally. As the flowrate is increased, stable equilibrium may be lost by either divergence (static ...
