PHYSICAL PARADOXES 



A communicates with the steam boiler or 

 exhaust, which supplies it with steam. From 

 its upper end a small jet of steam issues rapidly 

 upwards. B communicates with the cold water 

 supply and leads into an annular chamber 

 C C, which delivers an annular jet of cold 

 water surrounding the steam- jet. In contact 

 with this cold water the steam-jet is instantly 

 condensed into water, forming the fine stream 

 of rapidly moving water already described. 

 This stream has energy enough to carry itself 

 and the cold water which mixes with it into the 

 passage D, which communicates with the steam 

 boiler ; the stream, as it enters the wider part 

 of this passage, gradually diminishing in speed 

 and increasing in pressure until it is able to 

 overcome the boiler-pressure.
