The reason is explained using the classical waterhammer theory. The waterhammer equations, which include the friction term, are solved by the method of characteristics. Charts are presented for determining the maximum head fluctuation in the pipe line system with two valves which close simultaneously at the same constant speed. These charts include the cases with steady state friction losses of 30, 50 and 80％ of the reservoir head, and with no friction loss.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0442000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TR-442","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"上智大学理工学部"},{"subitem_text_value":"航空宇宙技術研究所計測部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Sophia University"},{"subitem_text_language":"en","subitem_text_value":"Instrumentation and Control Division, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"池尾, 茂"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"池谷, 光栄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"IKEO, Shigeru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"IKEYA, Mitsuei","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-29"}],"displaytype":"detail","filename":"naltr00442.pdf","filesize":[{"value":"860.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00442.pdf","url":"https://jaxa.repo.nii.ac.jp/record/44692/files/naltr00442.pdf"},"version_id":"d52737a9-e042-4e8b-888a-47e015dd0613"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"二個の弁を有する管路系に対する水撃線図","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"二個の弁を有する管路系に対する水撃線図"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"44692","relation_version_is_last":true,"title":["二個の弁を有する管路系に対する水撃線図"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:52:32.512916+00:00"}
