瓦斯管路流量計(jì)算表

1、瓦斯管路流量計(jì)算表中梁山煤電氣有限公司礦業(yè)分公司北礦通風(fēng)隊(duì)使用說明：1.本表根據(jù)水力學(xué)公式推出井下瓦斯管路流量公式為： 按此公式計(jì)算出混合瓦斯流量。2.將測(cè)得的管路動(dòng)壓（公厘水柱）和瓦斯?jié)舛戎涤诒韮?nèi)查找出相應(yīng)的混合瓦斯流量，再乘以瓦斯?jié)舛?，即得純瓦斯量，m3/min。3.本表適合目前井下抽放情況，若個(gè)別從表中查不到相應(yīng)的數(shù)據(jù)時(shí)，則可用上述公式在附表中查相應(yīng)混合瓦斯容重r代入公式，即可計(jì)算出混合流量。我礦瓦斯管主要巷道平均流速值（用中心點(diǎn)測(cè)法）測(cè)定地點(diǎn)動(dòng)壓范圍ReN平均流速m/min鉆場(chǎng)0.100.50160006.90.814Vmax0.501.001090007.30.832Vmax各異支管
