www.dm.gov.ae= Critical wind speed for vortex shedding . V. m (z) = Height-dependent average wind velocity . w (z, t) ) = Dynamic component of wind velocity – turbulance. w. max = Maximum turbulance velocity . z. o = Surface friction coefficient . z. min = Minimum height in which surface friction is constant . z. r = Reference height

Unsteadiness is measured by the Strouhal number, ba-sically the period of the spontaneous oscillations versus the transit time of the ow across the obstacles. St˘ @ tu uru Typical Strouhal numbers are usually well below 1, indicating that inertia

www.emerson.comThree vortex shedding cycles or 300 ms, whichever is greater, maximum required to reach 63.2% of actual input with the minimum damping (0.2 seconds). Turn-on time HART analog Less than four (4) seconds plus the response time to rated accuracy from power up (less than 7 seconds with the MTA Option). Transient protection
