Max velocity of steam in pipe

Web5 mei 2024 · So, if we have a wind velocity of 10 m/s and we know that our pipe has an OD of 0.3238 m (see Part 1 where we calculated natural frequency) the VIV frequency is 0.22*10/0.3238 = 6.79 Hz. ... So, let’s say our 5 m pipe has a maximum vibration amplitude of 0.5 mm pk-pk. The bending stress is.
