20.500.12556/RUL-127250 Merjenje prostornine in gostote teles z metodo hidrostatičnega tehtanja Volume and density measurements of objects by hydrostatic weighing method Natančen način merjenja prostornine trdnega telesa je tehtanje v tekočini ob znani masi telesa. V tem delu je pozornost usmerjena v tehtanje v tekočini, medtem ko je bila konvencionalna masa določena predhodno po akreditiranem postopku. Kot referenčna tekočina je uporabljena demineralizirana voda. Njena gostota je določena z merjenjem temperature. Iz prostornine in mase telesa je nadalje mogoče izračunati gostoto telesa. V izračunih so upoštevane številne korekcije, ki so posledica neidealnih pogojev pri merjenju. Merilna negotovost je analizirana na podlagi ovrednotenja posameznih prispevkov. Izvedene so bile meritve prostornine in gostote na petih različnih trdnih telesih v laboratoriju podjetja LOTRIČ Meroslovje d.o.o. An accurate procedure of measuring a volume of a solid object is hydrostatic weighing in a liquid while knowing its mass. In this work the focus is on weighing in the liquid while the conventional mass of the object was determined by an accredited procedure in advance. As the reference liquid demineralized water is used. Its density is determined by measuring its temperature. From volume and mass of the object it is further possible to calculate the density of the object. In the calculation, many corrections which are consequences of non-ideal measuring conditions are taken into account. Measurement uncertainty is analysed based on the individual contribution evaluation. Volume and density measurements were performed on five different solid objects in the laboratory of LOTRIČ Meroslovje d.o.o. company. prostornina teles gostota teles hidrostatično tehtanje merilna negotovost volume of objects density of objects hydrostatic weighing measurement uncertainty true false false Slovenski jezik Angleški jezik Zaključna naloga 2021-05-29 08:15:03 2021-05-29 08:15:07 2022-09-06 03:50:21 0000-00-00 00:00:00 2021 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 118041 61942531 2644.pdf 2644.pdf 1 7D93273F53C9EC2EE1B3BB88D69B85D8 31d10d9eaa62cee6cdcd82ecac01e14f6903f4a33c6fc81d4864cb44e6ceb206 273d437d-c045-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=143557 Fakulteta za matematiko in fiziko 0 0 0
