As the vacuum time and dyeing time increased, color change and dye uptake first gradually increased until water began to be discharged, leading to a decrease of the pressure gradient
in the log, and then decreased.
First, the value for height (h) does not appreciably change because the flow through the tracheobronchial tree originates from the pressure gradient
between the mouth and the alveoli.
found pressure gradients
accurate to within 2% of those for the C-Y model.
Although it can be invasive and uncomfortable for the patient, renal venography combined with measurement of the pressure gradient
between the left renal vein and the IVC is the gold standard for demonstrating renal vein hypertension.
The fluid is driven by a uniform pressure gradient
parallel to the channel plates and the entire flow field is subjected to a uniform inclined magnetic field of strength [H.
Rated to 450 deg F (232 deg C) the PressureXpress-HT tool provides accurate pressure gradients
and overall data quality not achievable by conventional high-temperature formation tester tools.
Synoptic charts emphasized the divide between sub-Tropical and Temperate with stormy conditions south of the Cape which have been restricted from much northward extension, yet with excessive pressure gradients
recurrent across the Southern Ocean southward to the Polar zone.
Of the 2 patients (#4 and #5 in the Table) who had both first and second CABG procedures at BUMC, both had small (16 mm Hg in #4 and 8 mm Hg in #5) peak systolic pressure gradients
between the left ventricle and aorta at the time of the second isolated CABG procedure.
1995) considered, as in this study, that this circulation in large stratified lakes is a result of isotherm shape near the lake bottom, causing internal pressure gradients
resulting in geostrophic cyclonic circulation.
In what follows the measurement locations, pressure differences, pressure drops, and pressure gradients
are referenced with respect to their axial position relative to the inlet and outlet of the U-bend.
The corresponding pressure gradients
are also shown.
Patients with cirrhosis and esophageal varices have hepatic venous pressure gradients
of 10-12 mm Hg.
