Flow Resistance of Textile Materials
Textile Research Journal, 2003Part I of this series presented a new model for predicting the flow resistance of monofilament fabrics. In this part, the model is applied to the flow resistance of multi filament fabrics. Experiments show that flow resistance in multifilament fabrics can be modeled in general, but it appears that the method is not suitable for modeling flow resistance

Lung, 1989
In the past it has been generally assumed that pulmonary flow resistance (RL) increases with increasing flow and decreases with increasing lung volume. Recent work indicates that RL decreases with increasing flow, at least up to flow rates 3-4 times greater than those at rest, and increases progressively with increasing lung volume.

Resistance to fluid flow in veins
Journal of Clinical Monitoring, 1996We evaluated the resistance to fluid infusion in the veins of 118 adult patients after intravenous catheter insertion prior to elective surgery. Hydraulic resistance in veins was defined as the slope of the pressure-flow relationship obtained by measuring venous pressure at several fluid flow rates.

The Resistance to Blood Flow in the Capillaries
Canadian Journal of Physiology and Pharmacology, 1972The pressure–flow relations of single erythrocytes and of heparinized whole blood flowing through glass tubes 4–15 μm in diameter have been studied. Driving pressures ranging from 0 to 8 cm H2O were used to produce mean velocities of flow of 0–1000 μm∙s−1. The velocities were measured by high-speed cinemicrophotography.

Computer-controlled flow resistance
Medical & Biological Engineering & Computing, 1999A computer-controlled flow resistance (CCR), to be used in a computer-controlled lung model, is presented. Flow is forced through a slit between a cylinder and a sleeve around the cylinder. The resulting flow resistance depends on the width, circumferences and the variable length of the slit.

Resistance to Flow in Vascular Beds
Nature, 1958DR. S. D. CARLILL1 has attacked the standard concept of resistance to flow (R) as the ratio of the driving force (the pressure drop P across the bed) to the flow F, and advocates that the ‘dynamic resistance’, that is, the differential dP/dF be substituted. His argument seems to assume what he is trying to prove.

Resistivity of flowing salt solutions
Journal of Applied Physiology, 1965The longitudinal resistance of salt solutions flowing in rigid tubes is found to change by less than frac14 of 1% for flow velocities up to and exceeding the turbulent rate. The reduced resistance of flowing blood as contrasted to stationary blood is thus not due to altered resistance of the fluid proper rheoencephalogram; blood flow; impedance ...

Flow Resistance in Tracheotomy Tubes
Annals of Otology, Rhinology & Laryngology, 1973The role of the upper airway (the breathing passage above the trachea) in maintaining the normal junction of the respiratory system has been suggested by previous investigators. During a tracheotomy the upper airway is by-passed by a prosthetic metal or plastic tube which is placed into the trachea through the neck.

Flow Resistance of Inertial Debris Flows
Journal of Hydraulic Engineering, 2013AbstractThis work deals with the evaluation of the most suitable expression for the motion resistance of a debris flow. In particular, it focuses on inertial debris flows, i.e., granular-fluid mixtures in which the particle inertia dominates both the fluid viscous force and turbulence; it provides, through an order-of-magnitude analysis, the criterion ...
