What is the difference between actual, standard, and normal flow rates for gases?

Standard flow rate is a correction applied to an actual flow measurement based on a given temperature and pressure. The correction is applied using the ideal gas law. The most widely used value is 1 atmosphere (101.3 kPa) or 14.696 psia at sea level and 59 0F (150C).
