Na této straně naleznete několik možností výpočtu ventilu…Je možno vždy pro kapaliny a plyny vypočíst KV-hodnotu, průtok, Q a tlakovou ztrátu Δp. Pro plyny je nutno vždy rozlišit mezi podkritickým (p2 > p1/2) a nadkritickým (p2 < p1/2) výpočtem.
U všech výpočtů se jedná o zjednodušené vzorce, počítat se dá vždy jen s uvedenými jednotkami.
