（）二、设计资料1该教学楼共五层，层高4m，设男女卫生间各一。男厕设蹲式大便器11个，洗脸盆6个，污水盆2个。女厕设蹲式大便器11个，洗脸盆6个，污水盆2个。首层地面标高为0.00，室外地面标高为-0.30。2室外给水管道离外墙1.5m埋设，管径dn100，管中心标高为-1.0m，所提供的最低水压为300kpa。3. 消防用水由室外消火栓给水管道提供，室外消火栓给水管道离外墙2.0m埋设，管径dn100，管中心标高为-1.0，所提供的水压为395kpa。水带长度取20m。4. 室外污水管道离外墙3m，管径为dn300，管内底标高为-1.50-1.6m；室外雨水管道离外墙4m，管径为dn300，管内底标高为-1.80-2.0m。5min暴雨强度为520l/(s.万m)。三、设计计算过程（一）建筑内部给水系统设计计算1. 给水系统所需压力估算计算层数=45/37，kpa，所提供的最低水压为300kpa，仍考虑采用直接给水方式。2. 给水系统水力计算本建筑属于教学楼，故给水管道设计秒流量计算公式采用，其中=1.8。本工程采用upvc塑料给水管。卫生器具当量数确定：污水盆0.75，洗手盆0.5，小便器0.5，大便器延时自闭式冲洗阀6（计算时以0.5计，计算得到后附加1.2l/s）。根据给水管道系统图，确定计算管路，进行管道水力计算，计算过程列入表1。采用当量法计算计算原理参照建筑给水排水设计规范gb50015-2003（2009年版），采用公共建筑采用当量法
