It was a vertical water-tube boiler, constructed from four concentric tubes.
2.
In some cases concentric tubes form, one inside another.
3.
Multi-walled nanotubes ( MWNTs ) consist of multiple rolled layers ( concentric tubes ) of graphene.
4.
The thermodynamic behaviour of concentric tube heat exchangers can be described by both empirical and numerical analysis.
5.
Inside each column were three concentric tubes.
6.
Similar effectiveness relationships can be derived for concentric tube heat exchangers and shell and tube heat exchangers.
7.
For concentric tubes, this relationship simplifies to the difference between the diameters of the shell and the outer surface of the inner tube.
8.
An inductively coupled plasma ( ICP ) for spectrometry is sustained in a torch that consists of three concentric tubes, usually made of quartz.
9.
In the United States, Arthur Bramley at the United States Department of Agriculture improved on this design by using concentric tubes with different temperatures.
10.
According to Middleton, 1966, " an essential point is that air is drawn between the concentric tubes, as well as through the inner one ."
