某輪頂流航行,船速15kn,流速2kn,2h后相對(duì)計(jì)程儀讀數(shù)差為28'.0,計(jì)程儀改正率-10%,則該輪對(duì)水航程為()。
某輪順風(fēng)順流航行,船速18kn,流速2kn,風(fēng)對(duì)船舶航速的影響1kn,計(jì)程儀改正率-8%,0400計(jì)程儀讀數(shù)L1=100'.0,則2h后絕對(duì)計(jì)程儀讀數(shù)L2為()。
某輪船速14kn,順風(fēng)順流航行,流速2kn,風(fēng)使船增速1kn,0600計(jì)程儀讀數(shù)為100'.0,計(jì)程儀改正率ΔL=-5%,則2h后相對(duì)計(jì)程儀讀數(shù)為()。
某輪頂流航行,船速15kn,流速2kn,2h后相對(duì)計(jì)程儀讀數(shù)差為32'.0,計(jì)程儀改正率-10%,則該輪實(shí)際航程為()。
某輪船速18kn,航行2h后相對(duì)計(jì)程儀讀數(shù)差為34'.0,計(jì)程儀改正率ΔL=0%,已知該輪實(shí)際航程為32nmile,則該輪航行在()中。
