Hello Coilers,

I finally got around to rigging up a manometer to measure the pressure in
my hyperbaric gap.  I used "oxygen tubing" that I obtained from a doctor
friend and made a U loop of about 18 inches secured to a piece of wood.

I put some water in the tube, marked the static position, then turned on
the vaccuum cleaner compressor.  Much to my amazement, it proceeded to
blow the water completely out of the tube!  I've obviously got a lot
more pressure than I thought!!

Does anyone know what the relationship between inches of water and actual
pressure in PSI is?  I know what it is for mercury, since altimeters and
barometers commonly use it, but I can't find any info on water.
