Q693. In equation FF-1, is the value supposed to be standard cubic feet per minute, or actual cubic feet per minute?
A693. In the equation FF-1 in subpart FF, the reporter may use either standard or actual volumetric units for “V”, as long as temperature, “T”, and pressure, “P”, in the equation are based on the same condition. Thus if “V” is in actual cubic feet per minute, then “T” and “P” should be at the actual conditions at which “V” was measured.
