Dear Phil,
As I said to you. My velocity values should be regarded as maxima when
the temperature difference between ambient and final is at its highest
except where there are constrictions. Then the Venturi calculation
cuts in.
Remember, no mention has been said about horizontal flow though it was
factored into the ancient "Rule of Thumb" Calculations.
Anyway, what is the Max velocity for a 16 foot stack?
Best regards,
Ivor Lewis. Redhill, South Australia
