【Abstract】 The local hydraulic resistance of plumbing accessories for plastic-covered aluminum pipe (PAP) was measured experimentally and computed and compared with the prolonged resistance in different cases of building water supply. Finally the local water-head loss of accessories expressed in percentage of just prolonged distance of PAP has been recommended in this paper.更多还原
