Instead of approximation formula ln( E ( t )/ E (0)) = [( a − bt ) t /( c + T )] commonly used at present for representing dependence of pressure of saturated streams of liquid water E upon temperature we suggested new approximation formula of greater accuracy in the form ln( ...
In standard cup tests, the gradient of water vapour pressure is created by sealing a specimen of the test material of uniform thickness over the mouth of a cup containing either a saturated salt solution or a desiccant which acts as an internal humidistat to provide a constant relative humidity...
Calculate water vapor pressure using the Antoine Equation given a temperature. Includes a graph of pressure versus temperature.
Acoustic pressure field within the polymeric (PDMS) core–shell micro-bead and the surrounding water environment for the initial 25 ns of the process. Remarkable is the occurrence of a “close-to-hexagonal” tessellation pattern that, once disrupted by (acoustic) standing waves, leads to acoustic...

The gradient drop, also called pressure drop, was obtained using the equation: $$\Delta {{{\rm{P}}}={P}_{{in}}-{P}_{{out}}$$ (10) To evaluate the transporting capacity of microlattice scaffolds, computational permeability was calculated using the following formula: $$k=\frac{\upsil...
Mixtures of pyrene and eicosanoic acid have been studied by surface pressure-area (pi-A) isotherms and steady-state and time-resolved fluorescence spectroscopy. Addition of pyrene in a monolayer at the air-water interface did not affect the area of the film. Steady-state fluorescence spectra ...
Based on the empirical formula, the dynamic load of downhole perforation has been analyzed [8]. It is concluded that the dynamic pressure from perforation will increase the damage risk of downhole equipment of deep-water wells [9]. The perforation process is simulated by using the finite ...
Many investigators also used high-pressure liquid chromatography (HPLC) for Chla determination and the Chla value is found in column ‘Chla’. The only exception to lab-determined Chla are measurements from the Thetis profiler in Lake Geneva (Switzerland) where Chla associated with Rrs measurements ...
