convert pressure in leakage detection

how i can convert pressure data (bar) to hydraulic pressure (m) in matlab?

[VBBV]

Do you mean Hydraulic pressure head in m ? with respect to which fluid ? Water ? Or any other fluid e.g. mercury?

[VBBV]

1 bar = 1e5 N/m^2 = 760mm of Hg

in fact,i have olga pressure data(bar) and i wnat to convert it into Hydraulic pressure data(m) in matlab code.

the fluid is gas.

thank you

H=(P/ρg)+z

[fatemeh pahlavanzadeh]

ρ is density

P is pressure

H is hydraulic pressure

z is location variable or pipeline difference parameter
