Hi!
Pressure is equal to height x density. P (psi) = [30 meters x 3.28 ft/ meter x 12 inches/ft] x [62.4 pounds per cu. ft. x 1/1728] = 42.64 psi, which is roughly equal to 3 bars.
Best regards.

| Dear experts, Could you explain me that why there is big difference pressures between two gauges installed while hydro testing? The first pressure gauge shows 3barg less than the one installed in 30meters above. regards Ilan |
