Back pressureThis experimental study investigated the back pressure (Pback) versus flow (U) relationship for 10 different tubes commonly used for semi-occluded vocal tract exercises, that is, eight straws of different lengths and diameters, a resonance tube, and a silicone tube similar to a Lax...
In subject area: Medicine and Dentistry A shallow or “flat” head curve represents greater sensitivity between the pressure-flow relationship such that small changes in pressure elicit greater changes in flow with any given change in pressure. ...
Pressure-flow relationships were determined and biopsy samples taken. The vasculature was then injected with silicone rubber. Perfusion resistance, vascular filling with silicone rubber and observations made by electron microscopy were compared.关键词:...
1、流体力学与传热课件流体力学与传热课件Flow Rate-Flow Rate-Pressure Drop RelationshipsPressure Drop Relationships As the pores in the medium are normally small and rate of flow of filtrate is low, laminar flow conditions are almost invariably obtained. So, the relationship between the superficial ...
1. 1. The relationship between the intraocular pressure and different rates of infusion of fluid into the anterior chamber of cat eyes has been determined. In the living animal, the mean pressure/infusion relationship was found to have a positive curvature, while in the dead eye the steady ...
As renal perfusion pressure was decreased below 100 mmHg in volume-expanded and hydropenic , renal blood flow, superficial and deep cortical blood flow, and inner and outer medullary blood flow all decreased. The results of these experiments demonstrate that blood flow in both the inner and ...

The calculated elastic stress depended on the mean velocity. The relationship between the flow properties and the elastic properties was clarified, and the effect of surface tension was described by estimating the capillary number. 展开 关键词: Slit Dilute polymer solution Pressure drop Jet thrust ...
The flow rate and flow rate of the valve mainly depend on the diameter of the valve, and also on the resistance of the structure of the valve to the medium. At the same time, it has a certain internal relationship with the pressure, temperature and concentration of the medium of the val...
