As a result, it is important to analyze water hammer for the safety of the pipeline and for the control of water flow. In this paper, water hammer which occurred in the main pipeline was analyzed. Especially, in the case of multi-level valve operation, the variation of velocity and pressure was discussed. We clarified that under the multi-level valve operation, water hammer pressure is not always decreased. Fig. 10 is a chart analyzing water hammer at the beginning of the flow. And a computer program is shown which is able to deal with any valve operation.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"近年, 農業水利の分野においては, 管水路方式が多く使用されている. 水圧に対する安全性の確保と流れの管理上, 水撃解析は重要なものとなっている. 本論文においては, 幹線水路におこる水撃の解析を行った. 特にバルブを階段状に操作した場合の圧力変動と管内の流速変化が論述された. バルブを階段状に閉鎖した場合は, 必ずしも連続的に閉鎖した場合の水撃圧より小さくなるとは限らないことを明らかにしている. また, 送水開始時の流れを解析する簡易図表と任意のパルプ操作が考慮できる計算機のプログラムが示されている.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"香川大学農学部","subitem_publisher_language":"ja"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00038339","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0368-5128","subitem_source_identifier_type":"PISSN"}]},"item_10002_text_25":{"attribute_name":"WAID","attribute_value_mlt":[{"subitem_text_value":"1706"}]},"item_10002_text_26":{"attribute_name":"KEID","attribute_value_mlt":[{"subitem_text_value":"2583"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAlternatives":[{"creatorAlternative":"西山, 壯一","creatorAlternativeLang":"ja"}],"creatorNames":[{"creatorName":"西山, 壮一","creatorNameLang":"ja"},{"creatorName":"ニシヤマ, ソウイチ","creatorNameLang":"ja-Kana"},{"creatorName":"Nishiyama, Soichi","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{},{},{}]},{"creatorAlternatives":[{"creatorAlternative":"彌永, 孝一","creatorAlternativeLang":"ja"}],"creatorNames":[{"creatorName":"弥永, 孝一","creatorNameLang":"ja"},{"creatorName":"イヤナガ, コウイチ","creatorNameLang":"ja-Kana"},{"creatorName":"Iyanaga, Koichi","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":"2020-12-14"}],"displaytype":"detail","filename":"AN00038339_33_1_45.pdf","filesize":[{"value":"261.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN00038339_33_1_45.pdf","objectType":"fulltext","url":"https://kagawa-u.repo.nii.ac.jp/record/3184/files/AN00038339_33_1_45.pdf"},"version_id":"7e1c2d67-24c9-4247-90b1-bbb90fda987f"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"斡線水路における水撃作用の解析","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"斡線水路における水撃作用の解析","subitem_title_language":"ja"},{"subitem_title":"An analysis of water hammer in the main pipeline of irrigation project","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"11","path":["369"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2012-03-27"},"publish_date":"2012-03-27","publish_status":"0","recid":"3184","relation_version_is_last":true,"title":["斡線水路における水撃作用の解析"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2023-11-22T02:38:18.102932+00:00"}
