17 Membrane Pressure & Temperature Correction Tables
Technical & Engineering
To adjust from 60 psi (414kPa) to another pressure multiply
the production rate by the correction factor.
To adjust from 77° F (25° C) to another temperature, multiply
the production rate by the correction factor.
To adjust from pressure to standard conditions divide by
the factor.
To adjust from a temperature to standard conditions divide
by the factor.
