The degree of the wetted surface
is a function of the time needed to carry out the complete measuring procedure, as in Fig.
Congress enacted the act in 2011 to amend Section 1417 of the Safe Drinking Water Act (SDWA) and required that the wetted surface
of lead pipes, fixtures and plumbing fittings and fixtures sold for or installed in potable water applications not contain more than 0.25% lead by weight.
For example, the wetted surface
area determines the quantity of surfactant required to ensure complete particle coverage and accordingly, optimal particle dispersion.
Deviations of wetted surface
temperature from thermodynamic wet-bulb temperature are partially addressed in ASHRAE Standard 41.14 in a discussion of wet-bulb temperatures at various surrounding air velocities.
A stainless steel weatherproof housing, 12-20Ra wetted surface
and tri-clamp connection make the model types 2032, 2132 and 2232 the ideal choices for any critical sanitary pressure measurement application.
With its self-draining and cleanable design, the Micro Motion T-Series with smooth 15 Ra wetted surface
finish is ideal for accurate measurement in pharmaceutical, food and beverage, and other hygienic applications.
The Model CMM flow meter offers an array of wetted surface
materials for service in harsh fluids--from water to corrosives to hazardous safety-sensitive fluids.
Kumar Wickramasinghe and his colleagues at IBM Almaden Research Center in San Jose, Calif., have demonstrated that DNA molecules separate according to their lengths as they move along a spike's wetted surface
. Moreover, the scientists have used the spike's point to lay down a nanoscale pattern of molecules.
The Rosemount 4500 Sanitary Pressure Transmitter features both 3-A and EHEDG approvals and provides a smooth, crevice free housing design with high quality electro-polished wetted surface
It allows pipetting from the top of the liquid rather than the bottom of the tube or plate, which reduces the tip's exterior wetted surface
, thereby minimizing cross-contamination.
Recognizing the potential risks, the Cwmbran-based R&D team at Crane Process Flow Technologies (CPFT) has developed a tool which calculates the total wetted surface
area for a mix of valves and weirs, and for a simple comparison (as it turned out a frighteningly graphic picture of the magnitude of that risk) illustrates the conclusion as a length of hose.
