(1) At standard conditions STP (0˚C. 1atm).
(2) Pressure listed is at process temperature of 0˚C.
(3) Maximum flow rate is the lower of 80 m/s.
(4) Minimum values are determined from Table 12. The values in parenthesis show the minimum linear flow rates (Re = 20,000 or 40,000)
when they are higher than the minimum measurable flow rate.
