Spirometry and Flow-Volume Curves

Clinics in Chest Medicine, 1989
Spirometry is the best and most widely used pulmonary function test. Equipment recommendations are made and performance information about different types of spirometers is given. Methods for obtaining clinically applicable spirometric results for use in making diagnostic and treatment decisions are presented.

Pressure‐flow curves in infancy

Pediatric Pulmonology, 1985
AbstractCalibrated pressure‐flow (P‐V) curves were plotted by computer using data from both the plethysmographic method for measuring airway resistance and the esophageal balloon technique for measuring lung resistance. P‐V curves from 100 sick, healthy, and convalescent infants (age range 2 days to 19 months, weight range 0.9–10.4 kg) were classified ...

Polystyrene Master Flow Curves

Transactions of the Society of Rheology, 1974
Capillary extrusion flow curves of four anionic and five polydisperse polystyrenes have been measured at five temperatures between 170 and 237°C. The non-Newtonian flow curves of the narrow distribution polymers can be represented by a common master curve in terms of the viscosity ratio (η/η0) and the product of shear rate and a relaxation time.

Flow in Narrow Curved Channels

Journal of Applied Mechanics, 1980
The flow through narrow, arbitrarily curved channels is formulated using intrinsic coordinates. An exact solution exists for constant curvature or circular arc boundaries. A perturbation scheme is used for the case of small, periodic curvature. The velocities and flow rates depend on both the curvature amplitude and the wave number.

Laminar Flow in Curved Pipes

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1969
AbstractSteady laminar flow in a curved pipe of circular cross section is investigated. It is assumed that the flow consists of a frictionless central core surrounded by a boundary layer. A formula for the friction factor of a curved pipe is derived, and the discharge coefficient for a 360‐deg elbow flowmeter is discussed.
