【简答题】
某工业架空热力管道工程由型钢支架工程和管道工程两项工程内容组成。由于现行预算定额中没有适用的定额子目，需要根据现场实测数据，结合工程所在地的人工、材料、机械台班价格，编制每10 t型钢支架和每IO m管道工程单价。 若测得每焊接1t型钢支架需要基本工作时间为54小时，则辅助工作时间、准备与结束工作时间、不可避免的中断时间、休息时间分别占工作延续时间的3%、2%、2%、18%。若除焊接外，对每吨型钢支架的安装、防腐、油漆等作业所测算出的人工时间定额为12工日，则各项作业人工幅度差取10%。 若工程所在地综合人工日工资标准为22．50元，每吨型钢支架工程消耗的各种型钢为1．06 t(每吨型钢综合单价3600元)，消耗其他材料费为380元，消耗各种机械台班费为490元。{Page} 根据场景，回答 44～47 题： 第 44 题 工人完成一定产品的施工工艺过程消耗的时间是（ ）。
