Non-Instantaneous Closure and Opening
Chapter
Abstract
In practice, valve closure is rarely instantaneous. However, as was mentioned in Section 3.6, the maximum pressure rise near the valve is the same as for sudden closure when the time of closure T is equal to or less than the critical time μ. The increase of pressure builds up during the time T.
