Objemov\u00fd pr\u016ftok<\/strong> je objem kapaliny (plynu nebo kapaliny), kter\u00fd projde za dan\u00fd \u010das definovan\u00fdm pr\u016f\u0159ezem (nap\u0159. potrub\u00edm).

Standardn\u00ed jednotkou pro objemov\u00fd pr\u016ftok<\/strong> je m\u00b3\/h. Objemov\u00fd pr\u016ftok se vypo\u010d\u00edt\u00e1 podle n\u00e1sleduj\u00edc\u00edho vzorce: V = vA<\/em><\/strong> * A <\/p>\n\n

Term\u00edn podtlak<\/strong> ozna\u010duje tlak v definovan\u00e9m objemu, pokud je ni\u017e\u0161\u00ed ne\u017e tlak okoln\u00edho prost\u0159ed\u00ed<\/strong>.<\/p>\n\n

Pou\u017eit\u00ed term\u00ednu vakuum je vhodn\u00e9 pouze v p\u0159\u00edpad\u011b, \u017ee existuje referen\u010dn\u00ed tlak.

Pokud je v\u0161ak prostor omezen (nap\u0159\u00edklad potrub\u00edm), vznik\u00e1 definovan\u00fd podtlak v z\u00e1vislosti na objemov\u00e9m pr\u016ftoku<\/strong> a pr\u016fm\u011bru potrub\u00ed. Princip \u010dinnosti vysava\u010de je zalo\u017een na tomto typu vytv\u00e1\u0159en\u00ed podtlaku. Sk\u0159\u00ed\u0148 vysava\u010de obsahuje dmychadlo, kter\u00e9 nas\u00e1v\u00e1 vzduch p\u0159es vakuovou trubici a vypou\u0161t\u00ed jej na druh\u00e9m konci. Vznikl\u00fd podtlak nas\u00e1v\u00e1 okoln\u00ed vzduch, a tedy i \u010d\u00e1ste\u010dky ne\u010distot<\/strong> do vysava\u010de. Podtlak se zvy\u0161uje, kdy\u017e pr\u016f\u0159ez z\u016fst\u00e1v\u00e1 stejn\u00fd a dmychadlo je v\u00fdkonn\u011bj\u0161\u00ed. Tot\u00e9\u017e plat\u00ed, kdy\u017e se pr\u016f\u0159ez zmen\u0161\u00ed a v\u00fdkon dmychadla z\u016fstane konstantn\u00ed. <\/p>\n<\/div>\n\n\n\n
