Answer Posted / n bala krishna
When a shedder bar is placed in a fluid, Karman vortices
are generated on the downstream side. The vortex frequency
is proportional to the flow velocity, and corresponds to a
specific range of Reynolds numbers.The vortex frequency (f)
is calculated by the formula; f=St*v/d
v: flow velocity, d: width of shedder bar, St: Strouhal

Calculate the maximum pressure drop that can be allowed to occur across a control valve, so that we can prevent cavitation / flashing from occurring. Use the following formula: Δ P allow = Km (P1 – PvapourA) where, Δ P allow - the maximum allowable differential pressure for sizing purposes, or terminal pressure drop; Km- the valve recovery coefficient from the manufacturer’s catalogue; P1 - absolute inlet fluid pressure; PvapourA - absolute fluid vapour pressure at the inlet temperature; Use Atmospheric pressure = 101.3 kPa, P1 = 1200 kPa(g), PvapourA = 4 kPa, KM = 0.72
