Ve\u010d o tem<\/a><\/div>\n<\/div>\n\n

\u010co je to objemov\u00fd prietok?<\/h2>\n\n

Objemov\u00fd prietok<\/strong> je objem kvapaliny (plynu alebo kvapaliny), ktor\u00fd sa pohybuje za dan\u00fd \u010das cez definovan\u00fd prierez (napr. potrubie). Aby sa tento pohyb mohol uskuto\u010dni\u0165, mus\u00ed v\u017edy existova\u0165 tlakov\u00fd rozdiel medzi aspo\u0148 dvoma priestormi\/objemami. V pr\u00edpade sacieho zariadenia objemov\u00fd prietok opisuje mno\u017estvo vzduchu, ktor\u00e9 prete\u010die sac\u00edm potrub\u00edm za dan\u00fd \u010das. S objemov\u00fdm prietokom sa stret\u00e1vame aj v ka\u017edodennom \u017eivote, napr\u00edklad pri vodovodnom koh\u00fatiku, v riekach a potokoch, ale aj vo forme plynov: vo vzduchu, v klimatiz\u00e1ci\u00e1ch a ventil\u00e1toroch. <\/p>\n\n

\"výpočet<\/figure>\n\n

\u0160tandardnou jednotkou pre objemov\u00fd prietok<\/strong> je m\u00b3\/h. Objemov\u00fd prietok sa vypo\u010d\u00edta pod\u013ea tohto vzorca: V = vA<\/em><\/strong> * A <\/p>\n\n

V = objemov\u00fd prietok | vA<\/em>= priemern\u00e1 r\u00fdchlos\u0165 pr\u00fadenia [m\/h] | A = plocha prierezu v mieste v [m\u00b2]\n\n

Pri prietoku vzduchu<\/strong> 2 000 m\u00b3\/h teda definovan\u00fdm \u00fasekom potrubia prete\u010die 2 000 metrov kubick\u00fdch vzduchu za hodinu. <\/p>\n\n

Napr\u00edklad: prietok 2 000 m3\/h pri r\u00fdchlosti 22 m\/s (78 km\/h) v potrub\u00ed s priemerom d180 mm alebo pri r\u00fdchlosti 18 m\/s (64 km\/h) v potrub\u00ed s priemerom d200 mm. <\/p>\n\n

\u010co je to depresia?<\/h2>\n\n

Pojem v\u00e1kuum<\/strong> ozna\u010duje tlak v definovanom objeme, pokia\u013e je ni\u017e\u0161\u00ed ako tlak prostredia<\/strong>.<\/p>\n\n

Pou\u017e\u00edvanie term\u00ednu v\u00e1kuum je vhodn\u00e9 len vtedy, ak existuje referen\u010dn\u00fd tlak. V s\u00fa\u010dasn\u00fdch norm\u00e1ch sa ako referen\u010dn\u00fd tlak pou\u017e\u00edva hodnota jeden bar(1 bar)<\/strong>. Starou jednotkou merania podtlaku bola atmosf\u00e9ra<\/strong>, od roku 1978 sa pou\u017e\u00edva bar. Ke\u010f\u017ee podtlak je ni\u017e\u0161\u00ed ako referen\u010dn\u00fd tlak, naz\u00fdva sa aj podtlak<\/strong>. <\/p>\n\n

Ak sa vzduch nas\u00e1va napr\u00edklad pomocou ventil\u00e1tora<\/strong>, nas\u00e1va sa vzduch, ktor\u00fd m\u00f4\u017ee sp\u00f4sobi\u0165 podtlak. Tento \u00fa\u010dinok je v\u0161ak takmer kompenzovan\u00fd pr\u00faden\u00edm vzduchu v neobmedzenom priestore. Ak je v\u0161ak priestor obmedzen\u00fd (napr\u00edklad potrub\u00edm), vznik\u00e1 definovan\u00fd podtlak v z\u00e1vislosti od objemov\u00e9ho prietoku<\/strong> a priemeru potrubia. Princ\u00edp \u010dinnosti vys\u00e1va\u010da je zalo\u017een\u00fd na tomto type vytv\u00e1rania podtlaku. Skri\u0148a vys\u00e1va\u010da obsahuje d\u00fachadlo, ktor\u00e9 nas\u00e1va vzduch cez v\u00e1kuov\u00fa trubicu a vyp\u00fa\u0161\u0165a ho na druhom konci. V\u00fdsledn\u00fd podtlak nas\u00e1va okolit\u00fd vzduch, a teda aj \u010dastice ne\u010dist\u00f4t<\/strong> do vys\u00e1va\u010da. Podtlak sa zvy\u0161uje, ke\u010f prierez zost\u00e1va rovnak\u00fd a d\u00fachadlo je v\u00fdkonnej\u0161ie. To ist\u00e9 plat\u00ed, ke\u010f sa prierez zmen\u0161\u00ed a v\u00fdkon d\u00fachadla zostane kon\u0161tantn\u00fd. <\/p>\n<\/div>\n\n\n\n
