Abstract
Description
本出願は、2016年11月4日に出願された米国特許出願第15/344,458号明細書の利益を主張する。米国特許第15/344,458号明細書は、その全体が参照により本明細書に組み込まれる。
・このシステムは、自動遮断弁340(図3)又は手動遮断弁を介して、被加圧水の外部供給から閉ざすことができる。
・システム内部の流体の温度及び密度は概ね一定とすることができ、また、システム内部で発生するプロセスが断熱的であるとみなすことができるように、このシステム自体を断熱することができる。
・漏れ口の形状(割れ、細長い切れ目、丸い開口部、等)に関わらず、漏れ口の断面積は、円形の面積として近似することができ、この円形の面積は、実際の漏れ口の表面積と一致する。
・開口部から出てゆく流量の変化の割合は一定とすることができる。この仮定は、言葉を換えると、破裂したときに漏れの位置で流量に瞬間的な変化が起こり得ることを述べている。
・管があまり分厚くないと仮定することができるので、漏れが存在している間にシステムが蓄積し得る何らかの摩擦損失については、一切考慮しない。
この反復プロセスは、水柱の高さがゼロに等しくなるまで続けることができる。
