Mesh pads allowable velocity

WTen the mesh is installed with the pad vertical or inclined, die maximum allowable velocity is generally used at 0.67 umes the allowable value for the horizontal position. 

V (separator) = Separator vapor velocity evaluated for the gas or vapor at flotving conditions, ft/sec V = Vapor velocity entering unit, lbs, per minute per square foot of inlet pipe cross section Va = Maximum allowable vapor velocity across inlet face of mesh calculated by relation, ft/sec Van Actual operating superficial gas velocity, ft/sec or ft/min, for tvire mesh pad Vu = Design vapor velocity (or selected design value), ft/sec... 

V ,ax = Calculated maximum allowable superficial gas velocity, ft/sec, or ft/min tvire mesh pad Vs = Superficial gas velocity, ft/sec Vsa = Separator vapor velocity evaluated for air-water system, ft/sec... 

Once K factor is determined, allowable vapor velocity (va, in ft/sec) thru wire mesh pad or vane pad can be calculated as follows ...
