If your bottle and reg are leak free there is no reason why it won't hold the preasure. I've had bottles last 6 months leak free with no problems. 2 tips though... 1 don't leave it on a marker, markers are best left with no preasure in them and any springs not under stress. 2 check your bottles date! If it's going away for a while make sure it doesn't run out of time before it needs re-testing.
138.60ft 2.31ft of water= 1 psi
6.9 kPa = 1 psi
1 Torr = about 0.02 psi
the weight of the water above. water in a 1" pipe 100' tall is 43 psi @ base of pipe. water in a 50' tank 100' tall is 43 psi @ base of tank. h x .434 = psi
1 bar is about 14.5 psi
There are 0.1450377378 pounds per square inch (psi) in 1 kilopascal (kPa).
Pounds per Square Inch or Psi is a unit of pressure or stress. 1 bar is equal to 14.50377 Psi.
never heard of it and can't find it anywhere on the net, not sure what you are talking about
27.71 inches of water column equals 1 psi
1 bar is 14.50377 PSI, so 2.8 bars is 40.610 PSI.
Pounds per Square Inch or Psi is a unit of pressure or stress. 1 bar is equal to 14.50377 Psi.
Um... there are 1 psi (lb/in2) = 144 psf (lbf/ft2) , if by (lb ft) you meant pounnds per square foot. then there is 1/144 psi in 1 (lbf/ft2)
