UNAPREĐENJE ODREĐIVANJA PROSJEČNOG PROFILA JAMSKE PROSTORIJE
Journal Title: UNKNOWN - Year 1992, Vol 4, Issue 1
Abstract
Određivanje otpora vjetrenoj struji u jamskoj prostoriji s dozvoljenom pogreškom mnogo ovisi od poznavanja točnih vrije-dnosti njezinih geometrijskih karakteristika: duljine, poprečnog presjeka i opsega. Eventualna pogreška kod određivanja profila prostorije povećava se kod preračunavanja otpora s trećom potencijom. Prikazana je konstrukcija prijenosne naprave za osvjetljavanje poprečnog profila prostorije kod fotografiranja. Određivanje geometrijskih karakteristika prosječnog profila dionice prostorije prikazano je analitički i grafički korišćenjem odnosa F3/U mjerenih profila.
