Witryna26 mar 2024 · In a first embodiment, a ventilator has a housing with a first fixed port and a rotatable shutter configured to cooperate with the housing to enclose an interior of the housing. The shutter has a first orifice at a first radial distance from its axis of rotation. A stationary plate abuts the shutter and includes a first stationary orifice configured to … WitrynaThe beta ratio is a very important design factor for designing orifice plates. Generally, the beta ratio is kept from 0.3 to 0.75. This is because keeping very high means the orifice bore and pipe bore are nearly the same. Keeping the orifice bore and pipe bore nearly the same will not generate sufficient differential pressure.
