Non-Instantaneous Closure and Opening,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 . is equal to or less than the critical time .. The increase of pressure builds up during the time ..作者: 采納 時間: 2025-3-24 22:47 作者: BARK 時間: 2025-3-25 03:05 作者: 軌道 時間: 2025-3-25 06:57
Waterhammer in Hydro-electric Supply Pipes,A surge tank is often constructed when there is a long pipeline supplying water to a hydro-electric power plant. We will consider the functions and design of surge tanks later.作者: Magnitude 時間: 2025-3-25 08:09
Theory of Mass Oscillation,The theory of the oscillation of the whole body of water in the pipeline and surge tank is based upon three fundamental equations: the dynamic equation, the equation of continuity and an equation giving the upward velocity of the water surface in the surge tank.作者: MAZE 時間: 2025-3-25 14:47

Finite Difference Methods II,In Chapter 11 we saw how various finite difference methods may be applied to the mass oscillations which follow sudden complete valve closure in a straightforward cylindrical tank with or without a throttle. The same methods—Pressel, Simple Arithmetic, Jakobsen and Escande—can be used for more complex cases.作者: Asymptomatic 時間: 2025-3-25 20:11
