Furthermore, four aspects, including outer diameter, surface roughness, extensibility and processing time of pipe reduction, which were influenced by the pushing force, were considered.
Because PCE is a volatile solvent, it was assumed that most would evaporate by the time of pipe installation.
PCE was expected to evaporate by the time of pipe installation; however, testing in 1980 revealed that large quantities of PCE remained in public drinking water supplied by VL/AC pipes.
It is shown that proton solid-state NMR transverse magnetization (T2) relaxation analysis is the most sensitive tool for determining changes in PPR samples that are caused by storage time of PPR pipes under hydrostatic pressure.
The start-up time of heat pipes with filling ratios ranged between 50 and 70% in the evaporation section increased with the increase of the filling ratio and heating temperature, but the small inclination angle had a negative effect on the start-up performance.
You've endured the crushing anomie of walking a neon-lit aisle at a supermarket while "It's the Most Wonderful Time of the Year" pipes in through ceiling speakers as you decide whether to shell out for the brand-name night-time sniffling, sneezing, coughing, aching, stuffy head, fever, so-you-can-rest medicine or stick to the generic.
"Internet traffic is very bursty by nature, that is, for a brief period of time, there is data movement, and for that brief moment of time, the pipe is completely full, and as a result, the companies scale for such peaks".
The flow rate calculation is used to determine the residence time of water in each pipe segment and to determine the direction of PCE-contaminated water flow through the system of connected pipe segments.
By the time of King John, the Pipe rolls were growing unwieldy, as too many fines and fees were being recorded, making the finding of information in the rolls difficult.
We chose sampling sites at locations where taps would be frequently used, thereby limiting the storage time of water in delivery pipe networks.
Lemma 3 is correct for layer i1, and therefore, the starting transmission time t i 1 j 1 of pipe P i 1 j 1 is no more than Depth(G[U∪C],i1)+54T r-j1), i.e., t i 1 j 1 ≤ Depth ( G [ U ∪ C ], i 1 ) +54T r-j1r - j 1 ) ; recall that r is the maximum rank, i.e., r a n k(s)=r.
